This Knox Rose dress is fabulous, but it no longer fits me. It is a size medium and best fit when I was a size 10. It measures 38" around the bust, 30" around the waist, and is about 40" long from waist to bottom hem. The material is 100% rayon. I washed it in cold water on delicate and hung it to dry. It's in excellent condition with no signs of wear. It comes from a pet-friendly and smoke-free home.
