This is a dress I purchased on Amazon a few years ago and have worn a few times. There is no material label, but I was told it was silk when I bought it. It is see-through. Material: 100% Silk The fabric is thin, quick-drying, soft, highly breathable, and doesn't get stuffy. It can be used as pajamas, loungewear, or a slip. There is a fray on the back (see image 7). Waist: 27cm Length: 84cm The length includes the shoulder straps. Please note that these measurements are approximate due to being taken by a layman. Please be aware that this item has been stored at home and has wrinkles, so please consider this before purchasing.
