The fabric is cool, but the part below the waist has a lining, so it can be worn on its own. A string in the same color as the dress is included, and can be tied at the waist (see photo 4). For reference, the dress length is knee-length on the seller, who is 154cm tall. There are no noticeable stains, but please understand that this is a used item before purchasing. #dress #floral
