The crown is attached (like a hood), so you don’t have to stress that you’ll lose the “accessory” part of the costume getting lost halfway through the evening. And the open-ended feet simply fit over whatever shoes your kid is wearing, so you don’t have to worry about it being too big or small.

Halloween, Thanksgiving, Monday... You don’t need a special occasion to dress your baby in this absolutely delightful flamingo costume. It’s one piece (the headpiece is attached), and has button snaps at the bottom to make diaper-changes easier. Take note that you’ll have to find your own pair of tights or leggings as the legs aren’t part of the costume.

If you’re looking for something your kid can literally wear day-to-day, this sweatsuit with skeleton print is cool, casual, and most of all, comfortable. It’s definitely the kind of thing they’ll want to wear to school regularly.

Thanks to the release of the Teenage Mutant Ninja Turtles: Mutant Mayhem movie earlier this year, you’re going to see tons of kids (and adults) dressed as one of the crime-fighting mutated turtles. This Ninja Turtle costume has a little more padding than most versions for young kids, and the shell is removable for convenience.

It might be tricky to sit down in this thing, but it’s a great all-in-one costume that doesn’t require you to chase down additional accessories to pull off. The headpiece is separate, so your tot can take it off if they need a breather or have an itch. The ‘hover pram’ is attached to the jumpsuit.

Your baby’s too young to appreciate Star Wars, but you’re not. This adorable Ewok costume will keep yout little one nice and cozy during Halloween festivities if the temperature dips, and dressed as the original cutest Star Wars character.

Picture how epic it would be if a bunch of kids from the neighborhood or your family dressed up as a colony of bats. This simple, comfy look is basically a one-piece sweatsuit with wings and it’s got cozy comfort written all over it.

Kids with a sense of humor will love this muscle man costume to show off their ‘muscles,’ and the padding will help keep them warm on a chilly night.

Dressing your little duckling up as an actual duckling will never get old. This one has a lot of extra padding that will make your tot look even more adorable, and also keep them warm. If your kid is a little bit older, there are cozy duck onesie costumes for them as well.

When I was a kid, Sonic the Hedgehog only existed as a video game. The recent boom of movies and shows about the super fast Hedgehog means there’s a fresh new wave of young Sonic fans, and if they want to dress as him, this cute costume is a solid choice.

There’s nothing stinky about this adorable skunk costume that will keep your baby in a cozy fleece hug on Halloween. And if you think the front is cute, the back is just as good — maybe even better.

Ok, this is a pretty awesome costume for kids that could probably even double as pajamas. The only downside is that the tiger slippers pictured are not included, but you could grab them for $16, also from Old Navy.
