Not Just for Halloween 💚
It's a costume, sure — but it's also the warmest, softest thing your baby will own this winter. Cold-morning walks. Grandma's house. Movie night on the couch. Every single day until they grow out of it.
✦Halloween & trick-or-treat photos
✦Cozy winter sleepsuit
✦Stroller walks & family visits

"My 8-month-old wore this for Halloween and then refused to sleep in anything else for two weeks. It's SO soft. Bought the 12–18M for when he grows."

"Dad here. The zip goes all the way down so nappy changes are actually easy — most costumes are a nightmare. Got 200 likes on the photo."

★★★★☆
"Gorgeous quality, thick and warm. Took a star because it ran slightly big on my 9-month-old — order your usual size, not up, if your baby is small."
