Costumes for Kids Online

Kids love to dress up. Not only does dress-up foster imagination, strengthen language and social skills, help advance storytelling and problem solving but role play has even been linked to the development of empathy in children.

Dressing up also has many physical benefits. Young kids love to pretend that they are running, jumping from building to building and wrestling with baddies. It’s a great activity that promotes healthy exercise and physical well-being.

With our kids’ costumes, your little one will enjoy endless hours of creative imagination and play, all while developing healthy life skills.

Most Popular Costumes

For girls, some of today’s most popular costumes include Disney princesses, like Elsa from Frozen and all the girl characters from Monster High. For boys, superheroes are almost always a hit. Our Batman, Spiderman and Hulk costumes are all very popular.

For very young children, our Australian baby costumes are some of the cutest things you’ve seen. We have adorable costumes for infants, including assorted animal jumpsuits, baby Angry Birds, a hot dog bun costume, baby elf onesie and more. Your little one is sure to be the talk of the evening!

Size Guide

All of our children’s costumes have photos, sizing information and accurate descriptions to ensure that the costume you choose will be a perfect fit for your child. We also have costumes sorted by baby, toddler, child and teen.

If you do wind up with a costume that doesn’t fit, just send it back to us within 30 days of your purchase, and we’ll gladly exchange it for you.

How do I know what size costume to buy?

All our kid’s costumes have a detailed sizing guide available for you to look at when making your purchase. All you have to do is measure up your little one(s) and ensure the costume that arrives is a fit first time, eliminating the need to go backwards and forwards to the store to try on different sizes and find that perfect fit. We also provide an age recommendation for each size. This is an estimate based on the average size of a child. However, be sure to check the measurements for each costume as these provide the most accurate way to assess the sizes.

Kids are always up to mischief and after adventure, so don’t fret that you’ll spend a fortune on a pricey costume only for the knees to be worn through and the stitching loose after a few wears. Costume Crazy only sells the best quality costumes, guaranteed to be so hard wearing and long lasting that you’re guaranteed to get value for your money when you shop with us.
