Halloween will be here before you know it, and of course, your kid will want to wear a costume. But what will they dress up as? When a witch or a dinosaur just won’t do anymore, you can always turn the page (literally) and consider a beloved fictional character as a cool costume to wear on October 31. If you want to bring fantasy to real life, your kid (and the whole family, really) can cast a spell as they knock on doors dressed up in Harry Potter costume ideas that are sure to score them a ton of candy.

It’s been over two decades since Harry Potter and the Sorcerer’s Stone was released in theaters, but that hasn’t slowed down the popularity of the wonderful wizard. After all, if your child is in elementary school, chances are they’ve read some of the book series as well. While your child might love the idea of dressing up as Harry or Hermione, Professor Albus Dumbledore or even the evil Lord Voldemort, it’s parents who will be the most pleased with Harry Potter Halloween costumes. Why? Well, for one thing, these costumes are built for the cold, thanks to lots of long sleeves and layers. And if your kid won’t wear a coat over their costume, it’s not a problem, because a cape will offer additional coverage on chillier Halloween nights and make the outfit even more authentic.

Plus, unlike other Halloween costumes which your child might just wear once, Harry Potter Halloween costumes are perfect for playtime dress up. So take a look and see which of these Harry Potter costumes for babies, kids, and grown-ups puts you under its spell.


Hedwig owl costume

Okay, so this isn’t technically a Hedwig costume. But for the sake of getting a baby in on the Harry Potter costume fun, you can pretend. This adorable little owl costume is so similar to the playful pet from the movies, no one will even notice. If you need extra warmth, put a white onesie like these ones and white leggings underneath. The wings and the head are separate attachments so they can be easily taken off, but your baby will feel like they’re just wearing a onesie.


Kids Gryffindor costume

Little wizards will look incredible in this adorable, high-quality Pottery Barn Kids Gryffindor costume this Halloween. The three-piece costume comes with a black cloak as well as a tie and a scarf in the traditional red and gold colors. For kids who don’t want to be just an average Gryffindor wizard and are more interested in being Harry himself, you can purchase a pair of Harry’s glasses separately. While the black cloak will certainly help hide spills, you may want to wait until trick-or-treating to give your child this Harry Potter Halloween costume to your child because it can only be spot cleaned and air dried.


Kids Hermoine costume

Kids wanting to dress up as the leading lady of the Harry Potter franchise will love this Hermione costume that looks like it came straight from a movie set. Though it looks like the costume is made from separate, layered pieces, it’s actually all attached, including the robe (true magic, indeed). The illusion includes a skirt, vest, white shirt, red and gold tie, and Hermione’s robe. Since they’re not included, grab a pair of black knee-high socks and some black shoes to finish off the costume. This Harry Potter Halloween costume is made from polyester, so it needs to be washed by hand and line dried to keep it looking its best.


Kids Harry Potter Quidditch costume

This isn’t just an average Harry Potter Halloween costume, it’s actually a Gryffindor team Quidditch uniform (which is arguably even better). The kids costume comes with three pieces including a red game robe with the Gryffindor crest, a red and gold shirt, and a pair of brown fingerless gloves that are perfect for grabbing the golden snitch. Little team players can finish off the costume by wearing a pair of their favorite black or brown pants and some boots. And, if you want to go the extra mile, you can also purchase a broom to really make the look come alive.


Adult Professor Trelawney dress and robe

Maybe you’ve already mastered all the spells and potions in the book. In that case, why not be a professor? This costume is a replica of the clothes worn by the one and only Professor Trelawney, who could tell the future. If she could predict yours, she’d probably say there’s lots of doom and gloom headed your way — but since she’s often a bit off, the reality is probably that you’ll be eating a lot of candy in the coming weeks. This costume includes a dress, skirt, vest, glasses, and a headband.


Victor Krum hat for adults

This hat could be part of the perfect Victor Krum costume. This red long sleeve t-shirt would really pull it together. Krum played at the Quidditch world cup, so the costume may be easy to put together, but he’s kind of a big deal. The hat is adjustable, one size fits most, and very comfortable.


Gryffindor jersey

Maybe you have someone in your family who’s less inclined to dress up in a robe and wave around a wand — that’s totally fine, because they can still be Team Gryffindor. This baseball jersey, which comes in a wide range of sizes — from extra small to 5XL — can be worn as an oversized tee by a smaller boy or girl, or it can be a perfect fit for a man. Plus, it’s very high quality and made of breathable fabric so it can be reworn again and again.


Luna Lovegood costume for adults

Everyone loves Luna Lovegood. The spunky, carefree wizard is a great costume choice for a girl or woman who identifies with her hippie-ish personality. The costume set comes with a jacket, skirt, a pair of leggings and a pair of leg warmers. So not only will you be representing one of the coolest characters in the franchise, you’ll be nice and warm while doing it!


Deluxe Harry Potter Hagrid plus-size costume

When it comes to the wizarding world of Harry Potter, no one is more beloved than Hagrid. Not only is he kind and gentle, but Hagrid is a true testament to courage and loyalty, traits that might get your teen a lot of treats on Halloween. The Deluxe Harry Potter Hagrid Plus Size Costume has the beginning basics for a fantastic evening. It comes with a faux suede jacket with an attached vest that has antique brass tone buttons running down the center. (And woot, the jacket even has two functional pockets with gussets and flaps, perfect for stashing extra Snickers.) Also included is a dark red knit shirt that has a Mandarin collar. Pair the costume with some pants, dark shoes (and a wig and beard, sold separately), and you’ll have the most lovable Hagrid on your hands.


Harry Potter women’s deluxe Bellatrix costume

Gone are the days of green-faced witches. Today’s witches are much more appealing — and super dangerous… like Bellatrix Lestrange. That’s what makes the Harry Potter Women’s Deluxe Bellatrix Costume so totally tempting to wear on Halloween. The costume comes with Bellatrix’s signature dress and corset combo, featuring an all-over swirl print on the gown that also has a hood, too. And while a corset might not sound quite so comfortable (particularly when you’re planning to sample a lot of sweets), the costume is made with a stretch jersey fabric backing to help you wiggle into and out it. To complete the look, pick up a wig and wand, so that, for one evening, you won’t be a Death Eater, but a candy eater.


Harry Potter Hedwig costume for toddlers

If you’re looking for a toddler Harry Potter costume, you *need* to transform your tot into Hedwig. And this adorable Harry Potter Hedwig Costume for Toddlers is a total hoot. Of course, in the books and movies, Hedwig is a gift from Hagrid for Harry’s 11th birthday and is a steadfast friend…right until (sob) the end. Dressing up your child as Hedwig means that they’ll be wearing a super soft white jumpsuit with feathers, and a detachable feathered wing cape. Your child can pretend to flap and fly around, but just be sure to spot clean this costume, since it can only be hand washed.


Harry Potter adult plus-size Sirius Black costume

As the titular prisoner in Harry Potter and the Prisoner of Azkaban, Sirius Black is a pivotal part of the Harry Potter series. That might explain why you won’t want to shapeshift (wink wink) once you get to wear this cool Harry Potter Adult Plus Size Sirius Black Costume. The 100% polyester costume comes with a prison-esque uniform of a jacket and striped pants and a shirt. The neck sign really sells the drama that comes with the story. The jacket is also looks stained, so it’ll look extra gross and scary; perfect for giving fellow trick-or-treaters the creeps while you go door to door with your kids on October 31.


Baby Harry Potter coveralls costume and hat

Although Harry Potter is already a tween when his story begins, that shouldn’t stop you from dressing up your baby as the wizarding boy wonder. In this cute baby Harry Potter costume, your child can wear a long-sleeve onesie that looks just like the iconic character himself. From the classic Hogwarts robe to the matching red beanie imprinted with Harry’s round glasses, your baby will look every bit the part of the protagonist from the films. And if you pick up Baby from their carriage, people will be pleased to see the Gryffindor emblem on the back of the costume, which will make your little one look just like Harry himself.


Child Gryffindor long-sleeve shirt

Let’s say that your child is at that stage where dressing up for Halloween in a complete costume isn’t cool any longer — but they still want some candy. That’s when a partial costume (kind of like this Child Gryffindor Long-Sleeve Shirt) can be bewitching. It has all the elements of a Harry Potter costume for Halloween sans the commitment. It features the Gryffindor emblem on the front with a mock peplum collar. How your child chooses to style the shirt (with a skirt and matching socks, like in the picture) or just a pair of jeans is entirely up to them.


Harry Potter Gryffindor Quidditch adult t-shirt

Your kids might be head over heels for Harry Potter, and perhaps you want to play along, too. When a full costume isn’t in the cards, you can still get dressed up in the Harry Potter Gryffindor Quidditch Adult T-Shirt. The 100% cotton shirt is officially licensed from Harry Potter and features the Gryffindor Quidditch team logo. The shirt shows that you’re a total team player, too, and is a lot easier to wear than scarlet and gold robes that the team typically wears. The cool thing is that you can wear this shirt as either a costume or as a regular shirt post-Halloween. Just be sure to machine wash the shirt cold so that it doesn’t shrink.


Wizard striped tie set

When you want to make your wizarding a family affair, there’s no easier way than by donning some items from Harry Potter’s signature look. For starters, you’ll need round glasses, a red and yellow-striped tie, and maybe even a lightning bolt-shaped scar. You can find all that in this fun Wizard Striped Tie Set that comes with all of the aforementioned goodies to get you looking like the wizard himself. There are three ties and glasses, along with five lightning bolt temporary tattoos. You might not even need to wear a robe or another Harry Potter Halloween costume since the glasses and tie will be enough for everyone to know that when it comes to wizarding, it’s all in the family.


Adult Voldemort costume

For adults wanting to embrace their inner bad guy, this costume of “he who shall not be named” is a perfectly dark option. It comes with a long black polyester robe and a super creepy mask that will scare muggle trick-or-treaters and wizards alike. It’s available for adults in XL and XXL sizes, so hemming skills may be necessary for shorter adults. Unfortunately, this costume doesn’t come with a set of gloves that look like Lord Voldermort’s unnerving hands but Amazon carries a pair that will definitely add some drama to the costume. All you’ll need is a good stick from the yard to serve as a wand for the finishing touch.


Toddler Dobby costume

Dress your toddler up as the family house-elf in this adorable handmade costume. It features a shirt-dress and a crocheted hat with ears, both of which are super comfortable (so your kid won’t complain about it being itchy throughout trick-or-treating). Reviewers rave over how wonderful this Etsy shop is to work with as well as the quality of the costume. Lindsey Kroger wrote, “Perfect! Shipped on time and arrived earlier than expected. The hat and dress fit exactly according to measurements (I needed a different size hat than dress and the owner was accommodating). Plus, it looks great with our family’s Harry Potter themed Halloween costumes. Couldn’t be more pleased!”


Baby Harry Potter Halloween romper

Sometimes Halloween costumes can be too bulky for little babies, especially if you live in a warmer climate, so a costume in the form of a onesie like this one can be a good alternative. This romper features symbols representing the different Harry Potter houses as well as a red hood with Harry’s signature lightning scar and glasses screen printed on. It has a sleeveless design and zips up the front to make outfit and diaper changes quick and easy. The best part about this Harry Potter Halloween costume, though, is that since it’s so casual it can be worn on a regular basis long after trick-or-treating.


Adult Women Gryffindor costume

Whether you want to channel your inner athlete or you just want to rep your favorite house, this adult Gryffindor quidditch Harry Potter costume is perfect. The costume, which comes with a top, leggings and a quidditch robe is designed to look like the character’s Quidditch uniforms. As with a lot of Halloween costumes, this one is made from polyester and needs to be hand washed and line dried. Also, it’s important to note that this costume sadly does not include the broom, but you can purchase this one separately.


Kids Harry Potter Halloween costume

Kids who want to look like the star of the franchise will love this Harry Potter Halloween costume that comes with a hooded robe and jumpsuit to match Harry’s everyday school look. Though the jumpsuit is one piece, it’s designed to look like multiple articles of layered clothing including a pair of pants, a sweater vest, white shirt, and the classic red and gold tie. One note, while this is a Harry costume, for some reason it doesn’t come with a pair of his iconic glasses. Not to worry, though, because you can buy them separately to complete the look.


Adult Professor McGonagall costume

McGonagall is among the best professors at Hogwarts, so her character deserves a high-quality costume like this one. The very realistic ensemble includes a jet-black dress, matching cloak, and her famous hat, which has a wire brim so that you can position it just right. The costume is available in both regular and plus sizes and is made from soft jersey knit fabric, so you’ll be comfortable all night. To complete the look, get yourself a magical-looking stick to serve as a wand and an old book that could pass as a spellbook (if you also happen to know how to cast spells, that’ll really sell the look).


Adult Snape costume

Harry may have been the star of the series, but if you’re wanting to dress up as the franchise’s hero, look no further than this deluxe Snape adult costume. The three-piece set is available in size XL and XXL and includes the robe, jacket, and cravat which are made from polyester (so they should be hand washed and line dried, if necessary). You’ll need to either find a really good stick in the yard or purchase a wand to go with the costume and, since a big part of Snape’s signature look is his hair, you may want to also invest in a wig to really complete your look.


Adult Harry Potter costume

Have you ever wanted to look at yourself in the mirror and say, “You’re a wizard, Harry”? Well, you can when you’re wearing this adult Harry Potter Halloween costume. The two-piece set is available in sizes medium, large, and extra large, and includes a hooded robe and a jumpsuit that is designed to look like a layered Hogwarts school uniform. You can leave the costume as is, or spring for a pair of adult-size Harry Potter glasses and draw a little lightning scar on your head to truly transform yourself from a muggle to the best wizard of all.


Toddler Slytherin Halloween costume

While Harry and his Gryffindor buddies may be the main stars of the series, there are plenty of other characters and houses to love, too. If your little one is more of a Slytherin house or Draco Malfoy fan, then this little deluxe Slytherin costume is just for them. It’s a cozy one-piece robe that’s available in toddler sizes 2T and 4T. Kids can wear their own white shirt and black pants and then wear the robe, which features the house’s signature green color and snake emblem, over the top. Take your tot outside to find the perfect stick to serve as a wand and they’ll look just like a Hogwarts student home for a holiday break.


Kids Ron Weasley Costume

Of course, a Harry Potter Halloween costume collection isn’t complete without Harry’s right-hand man and Hermione’s true love, Ron Weasley. Since there are a lot of Gryffindor costumes out there, change things up a bit with this costume that mimics Ron’s quidditch uniform instead. Even though it looks like the costume is layered, it’s actually a one-piece jumpsuit with armor detailing and the high-low hemmed cape. The costume also comes with a helmet with an elastic chin strap to make sure it stays in place throughout the quidditch match (or trick-or-treating). Since this set is pretty much a complete costume, you don’t need to purchase anything more to finish off the look, but if you want to be a little extra there’s no harm in accessorizing with a game-broom, too.


Toddler Harry Potter tutu dress

For a little toddler who loves Harry Potter and tutus, this dress will make for a perfect Halloween costume. The dress is one-piece and comes in the form of a onesie with button closure and lap shoulders to make it easy to put on and take off (and do diaper changes for toddlers who aren’t potty trained quite yet). The top of the dress features a screen print to make it look like a layered sweater with a collared shirt and a red and gold tie underneath. The tutu skirt is attached to the onesie and is made from tulle, so even though it’s made to be soft you might want to invest in some leggings or tights if your kiddo has sensory sensitivity to the fabric. Finally, the costume also comes with a little red satin headband to complete the Gryffindor look.


Harry Potter costume robe

If your kid already has a pair of dress pants, some black shoes, and a dress shirt, all they really need is this Gryffindor robe to create a Harry Potter Halloween costume. The robe comes in two sizes, S/M and L/XL, and has an open front (but if you want to close it for trick-or-treating, it’s nothing a simple safety pin can’t fix). There is a Gryffindor house crest on the front chest of the robe as well as a red-lined hood on the back, just like the ones worn in the movies. From there, grab a stick to serve as a wand and your kid will fit right in at Hogwarts.


Adult Hufflepuff costume robe

Maybe you see yourself as more of a Hufflepuff kind of wizard, which is fine because even though Harry is a Gryffindor, we need some strong, loyal Hufflepuffs in the wizarding world, too. In that case, consider this adult sized Hufflepuff robe for your Halloween costume this year. The high-quality robe has button closure at the neck, has a bright yellow lining along the lapels and the attached hood, and features an embroidered Hufflepuff house crest on the chest. Just add your own dress clothes underneath and you’ll look like you showed up for trick-or-treating right after finishing up a potions class at Hogwarts.

Whether or not these Harry Potter costumes will actually turn you into a wizard is TBD, but they’re cute nonetheless. Now, go and get everything you need to create your family’s Halloween look.
