Size & fit — read before ordering

This romper is made in one knit size, cut to stretch. It's best suited to newborns through about 18 months — use the product photos as your scale reference.

It works as a cozy pull-on onesie for everyday wear, not just for the holiday photo — since it's one knit size, keep an eye on fit as your baby grows, and supervise wear as you would with any knit garment.

Materials & care

A soft knit romper with an attached hood, finished with sewn trim and a back zipper for easy changes — available in five designs: Santa, Christmas Tree, Gingerbread Man, Snowman, and Elf.

Hand wash cold and lay flat to dry to protect the knit detailing. Skip the dryer and avoid wringing.

See it in motion

The star shape reads instantly, even at a glance.

Why the star shape works

Most holiday rompers are just a onesie in a seasonal print. This one is knit into an actual five-point star, so it's a cozy knit onesie and a costume in one — soft enough to live in, distinctive enough that nobody has to ask what it's supposed to be.

How it works

1

Zip and go

One smooth zipper down the back — on in seconds, easy to check on a diaper change too.

2

Wear it anywhere

Bedtime, nap time, or the living room floor — it's built to be lived in, not just posed in.

3

Stays comfortable

A roomy knit fit that works for a squirmy newborn just as well as a sleepy one.

Questions, answered

Will it actually look like the photos on my baby?

Every design is shown on the actual romper, styled the way it's meant to be worn. Fit and drape vary a little baby to baby, but the shape and detailing are exactly what you see.

Will my baby overheat in a full knit suit?

Keep an eye on them while they're wearing it, and watch for your baby's usual overheating cues — flushed cheeks, damp hair, fussiness. The hood can come down if they run warm.

Are the buttons and trim safe?

Yes — the buttons and trim are securely attached. As with any knit garment for a baby, we recommend supervised wear, whether that's for photos or everyday wear around the house.

Will it fit? There's only one size.

It's made in one knit size, best suited to newborns through about 18 months. Use the product photos as your scale reference.

Will it arrive in time for the holidays?

Please allow up to 12 days from order to delivery, so place your order with that window in mind for a holiday deadline.

Can we get matching designs for twins or siblings?

Yes — pick the sibling and twin pack above and choose a different design for each.

What if it's not right for us?

30 days from delivery for a full refund, no questions asked. Email support@cozycrittr.com with your order number.
