What Our Clients Say

4.5/5 from 7,761+ Happy Shoppers

This costume was super cute! I sized up because my 6yo is big for his age and glad I did! Everything was just the right size and fit

TK

Such a cute costume for 100 Days of School! It fit my 5-year-old perfectly and looked exactly as pictured. All of the accessories were great quality and really completed the outfit. The dress and cardigan are quite lightweight, so depending on the weather, there's plenty of room to wear a top and leggings or pants underneath to keep warm. Overall, we were really happy with it and received so many compliments!

Shannyn

My son was absolutely stoked with this costume! Shipping was fast and sizing is fantastic

Erlinda

Amazing costume with accessories. Always go one size bigger to your height as its tight. Shapewear made it fit.

Jess

Always go the next size up and you will have no problem. Size to height was a little tight and see through but shapewear made it fit ❤️

Jess

An amazing product. Great for kids. Shirt size is a little tight and sleeves can be scratchy but my daughter absolutely loved it. Great quality

Jess

Good Quality costume, good sizing for children.

Jess

Sizing is perfect for kids and good quality material.

Jess

The costume arrived really quickly and is excellent quality. The colours are bright and fun. My son tried it on just to make sure everything fit and it was perfect. My son loves it and he’s looking forward to wearing it for book week.

Mia

Thanks so much for making it so easy to dress up and play. The costume fit very well, was great quality and was perfect for the 80's murder mystery party.
