Pile material is appealing for its fluffy, towel-like texture. It's also highly absorbent, so you can wear it right after a bath without feeling sticky. This item will help you enjoy a comfortable bedtime♪ tutuanna I bought this at the store and wore the top twice and the pants seven times. There are a few pills on the inside of the pants. Please purchase only if you understand that this is a used item. I will compress it to make it compact for shipping. I am also selling room wear in different colors and styles.
