A simple costume that's equally hilarious as it is easy to throw together. All you'll need is a white maternity tee, some white leggings or pants, a frying pan and spatula, and a yellow fabric marker to turn your belly into the sunny side up portion of the egg.

This one is especially simple, all you need is a shirt in your preferred M&M color, some black pants, and the letter "M" to tape across your belly. Done and done.

A classic costume idea that you can't go wrong with is dressing like the mascot of Halloween itself: a pumpkin. Just grab an orange tee and some orange leggings and top it all off with a pumpkin basket. Turn your belly into a jack-o-lantern with some simple felt shapes cut out and glued to your shirt.

It doesn't get much simpler than the magic eight ball costume. Simply dress in all black — black tee, black leggings, black hat — and draw or tape a white number eight on your belly. Or take it one step further and tape a prediction on your back. What will your belly predict?

With a white tee, some red leggings or skirt (if you're feeling fancy), a red beanie, and a million tiny colorful craft balls and a hot glue gun, you can bet you'll be the cutest gumball machine at the party.

If you’re a fan of the iconic movie Juno, dressing like the movie’s main character this Halloween is a ridiculously simple way to get in the Halloween spirit. Dress in a cargo-style green jacket, striped tee, jeans, sneakers, and sport a messy low ponytail. Be sure to grab a Slurpee from the corner store to walk around with to complete the look.

You can dress just like those cute little guys that guard gardens and welcome visitors with their pointed hats and surly beards extremely easily this Halloween. Wear a simple bright blue tee with a large black belt above your bump and some black pants, topped off with a red hat and faux beard to have your pregnant self looking just like a garden gnome this Halloween.

Remember the scene in Willy Wonka and the Chocolate Factory (Yes, the original version — not the one with Johnny Depp.) where Violet Beauregarde blows up like a giant blueberry? Well, with your pregnant belly as the star of this simple costume, you can emulate this iconic scene by painting your face purple, donning a purple dress, and wearing a red bow in your hair.

Avocados are simply amazing. They can be spread on toast, made into dip, eaten with tacos — the options are endless. They also make a super simple Halloween costume for your pregnant belly. Wearing a green top and pants and cutting out a round piece of tan felt or paper to pin over your belly as the avocado pit will make you look just like an avocado that’s been sliced in half.
