Best of Etsy: Baby Costumes

Batman

Complete with a detachable satin cape and a reversible mask, this easy costume is perfect for a baby Dark Knight.

Gnome

Go woodland-chic with this little gnome costume. It's so simple … and so, so adorable. Best of all, the comfy brown pants can be worn year-round. (OK, so could the pointy hat and the bearded onesie … but that would be a little quirkier.)

To buy: The Wishing Elephant, $42

Hostess Cupcake

Just add a brown or orange beanie to this onesie, and your baby is ready to go. With the classic Hostess swirl, nobody will have any trouble figuring out what your babe is dressed up as.

Ice Cream Cone

With a cone, two scoops of ice cream (maybe a combo of orange and mint chocolate chip?), whipped cream and a cherry on top, this is possibly the most beautiful ice cream cone you'll ever see. You know, because your baby's face is nestled between ice cream layers.

Mermaid

OK, your kid might not be able to walk in this costume … but darned if she won't be the cutest baby on the block. The lacy bikini top only adds to the "awww" factor.

To buy: Squishy Couture, $37

Minion

With a beanie, diaper cover and cute little suspenders, your little one will look just like one of the minions from Despicable Me. As cute as the characters are in the movie, we know that your real-life baby will be even more adorable.

Owl

Whether you just get the hat and leg warmers that come with the basic package or add on a feathered romper and bodysuit, your lil' owl will certainly be a hoot.

To buy: Yarn N Doodles, $49

Rainbow & Cloud

OK, these costumes are a bit of a splurge, but … come on. For a pair of twins, is there anything cuter? And what little girl wouldn't LOVE to be dressed up as a rainbow? (You may have to do some convincing to get her sib in the cloud costume … but once it's on she'll go crazy for the dangly raindrops.)

To buy: The Costume Cafe, $120

Sushi

For babies so cute you could just eat 'em right up, a sushi costume is definitely the way to go. Complete with ginger, wasabi and that funny plastic grass, it'll be tough for anyone to tell the difference between your baby and the real thing.

To buy: The Wishing Elephant, $42

Bumblebee

All it takes to turn your baby into an incredibly beautiful little honeybee fairy is a tutu, wings and headband. OK, and a separately sold top, necklace and leg warmers. It's too cute!

To buy: Wren and Ribbon, from $56

Wonder Woman

There's nothing girly about this Wonder Woman costume. The mask, onesie and satin cape will make any baby girl look totally tough.

To buy: Just Kidn! Designs, $32

Cupcake

Great for colder climates, this cuddly fleece cupcake costume will keep your trick-or-treater warm … and totally adorable. There's even a cherry on top!

To buy: EZ Orange Design, $90

Firefighter

Crocheted from black, gray and neon yellow yarn, this miniature firefighter costume is also customizable—any letters or numbers can go on the hat. The little boots and suspenders finish off the look perfectly.

To buy: Connie's Crochet, $55

Fox

A soft hat (with ears!) and cuddly diaper cover (with a tail!) make up this cute baby fox costume. The ensemble will make your little guy or girl look super-sly.

To buy: Monarch Dancer, $38

Lion

Come on. Is there anything cuter than a baby with a giant lion's mane? The detail on this costume—namely, the felted hood—will have everyone oohing and ahhing over your babe.

To buy: Boo Bah Blue, $48

Milk and Cookies

When all the other kids are dressed up as pumpkins and ghosts, your little milk-and-cookies baby will certainly stand out. The fleece and eco-felt costume is as comfy as it is cute.

To buy: The Costume Cafe, $60

Mummy

This mummy onesie is perfect for the minimalist baby (or the baby who doesn't like wearing any extra layers, hats, gloves or other costume components). The patch sewn on the front makes it more special than a regular onesie, and totally passable as a costume.
