FAQs

What size should I pick?

Use your child's age as a general guide, along with the length and chest measurements in our size chart, since every child grows at their own pace. If you're between two sizes, we recommend going up for a roomier, more comfortable fit.

What is it made from?

Our onesie is crafted from soft, plush 100% polyester fleece — gentle on your little one's skin and cozy enough for all-day wear.

Is it easy to put on and take off?

Yes! The full front zipper makes dressing and changing fast and hassle-free, so no more struggling to get your little one ready.

Can my child sleep in it?

This is designed as a cozy costume and outfit for playtime and photos, not as dedicated sleepwear. We recommend removing hooded costumes before unsupervised sleep, for your child's safety.

What comes with my order?

Your order includes one hooded monster onesie with a front zipper, cozy horns, spots and a playful tail. Shoes and accessories shown in photos are not included.

How do I wash it?

For best results: zip it closed, turn it inside out, and wash gently in cold water. Avoid bleach, and air dry whenever possible. Always check the care label before washing.
