I purchased this at a Journal Standard store a few years ago, but I'm selling it because I haven't had a chance to wear it. Material: 100% cotton However, it has a light and airy feel, and wrinkles are not very noticeable. As you can see in the 5th and 6th photos, there is a stain? on one spot. The waist is not elastic, but a zipper type. Please feel free to ask any questions you may have＾＾
