White House Black Market Denim Dress with denim belt. Denim is comprised of 67% Cotton, 22% Polyester, 10% Rayon and 1% Spandex. It has quite a bit of stretch to it. I would say this dress runs large so it would fit a size 16 easily. This dress is NEW W/O TAGS. **Prompt acknowledgement of delivery with a rating is GREATLY appreciated!!**
