How to Choose the Right Costume Size for Your Toddler (BOO Size Guide)

Picking the right costume size matters for comfort, especially for younger kids who need room to crawl, walk, and play freely. Here's how to find the right fit for your child with BOO's animal character costumes.

How BOO sizes work

BOO costumes are sized by age range rather than standard clothing sizes (like S, M, L), since costumes need extra room for movement compared to regular clothes. Each character has specific age ranges based on its design:

BunBoo fits babies from 0 to 8 months, up through 1.5 to 3 years, in several incremental sizes as your child grows.

DinoBoo fits toddlers from 1 to 3 years, also available in incremental sizes (1 to 1.5 years, 1.5 to 2 years, 2 to 2.5 years, and 2.5 to 3 years).

ShaBoo, FoxBoo, and GriBoo are designed for older kids aged 4 to 7 years, with individual sizes available for ages 4, 5, 6, and 7.

How to measure your child

If your child is between two age ranges, it's usually best to size up rather than down, since costumes are meant to be worn over regular clothes during cooler months and should allow free movement for play. Check your child's height and weight against their actual age rather than clothing size, since costume sizing is based on body proportions for movement, not just height.

What if the size doesn't fit?

BOO offers a 48-hour return window after delivery. If a costume doesn't fit, items must be unworn, unwashed, and in their original packaging with tags attached. Contact BOO at mandt202666@gmail.com to start a return or exchange.

Quick tips for a comfortable fit

Choose a size based on your child's current age, not a couple of months ahead, since costumes are meant to fit now, not later. If your child is unusually tall or has a longer torso for their age, consider sizing up one level for extra room. For babies under 1 year old, look for costumes with full zips (like BunBoo) for easy, fuss-free changing.
