This is a baby romper from Kotori, purchased at Birthday. It's made of a sturdy fabric and is fleece-lined, so I think it's warm. I used to dress my baby in it with tights! I'm selling it because my baby has outgrown it. I don't see any noticeable stains or damage, but please understand that this is a used item before purchasing.
