Top and bottom set, Purchased in Hawaii about 20 years ago. Worn twice and then stored at home for a long time. There is no tag, but the material is believed to be cotton. It's a soft fabric. There is no size notation, but it's a wrap skirt that ties with a string and a top that can be adjusted with a string, so I consider it to be free size. Since it ties under the bust, the stomach area is exposed. The exotic pattern is perfect for Hawaii, tropical resorts, the beach, or camping. It will be folded for shipping, so please excuse any wrinkles.
