League of her own

infant halloween costumes

Not everyone wants to be Tinker Bell!

This pink, jersey-knit dress not only looked sharp on each tiny-leaguer but made getting in and out of the locker room quick work.

Being attracted to bold colors, the rookies loved the bright red belt and Rockford Peaches hat.

Their coaches were partial to the fact that the patches and belt were attached and that the buttons were printed on the uniform, noting that those details couldn’t go missing or find their way into little mouths.

All Smiles We’re pleased to announce that while each new recruit might not have the skills of the A League of Their Own players, they did love looking the part.

Lil Skunk

The onesie is made of super soft material and is trimmed with white faux fur. It zips up the back and has elastic cuffs, making changing easy.

A tail curls in the back, staying aloft by securing to a hook and loop strap in back. A little mohawk accents the face-framing headpiece, framed by pink-lined ears.

The suit has long sleeves and pants as well as little booties that cover the feet and a fluffy white belly. This costume is a great way to make a stinking cute impression at any event, costumed or otherwise.

Triceratops

The only problem with this costume is that it’s utterly unfair to other neighborhood kids; how is anyone else supposed to get any good candy when all of the adults are showering it upon this incredible little dino? 

This easy-to-wear outfit comprises a cozy jumpsuit, broken “egg,” and a pointed dinosaur tail.

The headpiece does double duty—it keeps your baby cozy and protected from the wind, while also turning him into a tiny triceratops! Stuffed horns, expressive eyes, and a cracked egg detail make this topper the tops!

Bumblebee

Yellow and black stripes traverse the long-sleeved jumpsuit, while easy snaps down the front make dressing your baby (and diaper changes) a breeze.

The hood of the costume pulls up to reveal a black bee head with yellow eyes and antennae.
