- Material: Fleece - Size: 90-110 Can be worn over clothes anytime in the cold winter. I bought it as fleece and used to put it on over pajamas after a bath or before bed. The soft material is warm, and the design colors are clear and very cute. I used it for about a year and it no longer fits, so I'm putting it up for sale. Since the size is 90-110, I think it can be worn for a long time. Please purchase only if you understand that this is a used item.
