Thank you for viewing! This is a silk dress. It's made of a stretchy material and feels great. It's machine washable! The waist belt is attached to the dress. It's very long, so you can arrange it in various ways. Perfect for a casual outing. I used to roll it up and bring it with me when I traveled. Please understand that this is a used item. Measurements (laid flat): Length: 98cm from shoulder 82cm from V-neck Width: 36cm Thank you very much.
