These are thin, long-sleeved, long-pants pajamas. It's a thin fleece fabric, or rather, a soft and warm fabric. Although thin, they are warm enough to wear even in winter in a warm room. They are perfect for children who dislike bulky clothing. Small pills have formed due to washing, but I don't think they are very noticeable. Used for one season (not worn every day). Would anyone who doesn't mind them be interested? Thank you. Color... Pink Sleeve length... Long sleeve
