4-ply silk crepe with hand cut lace and open back. Gatsby/20s/Garden Party inspired. This item is in excellent shape, only worn for a couple of hours. I am 5'6" 130lbs. The original measurements of the dress were (34.5 bust, 27.75 waist, and 41.5 hips) but was altered down as I lost weight (maybe an inch?). Built in bra (cups). Back is also more open (lower) than a standard Pemberly---but very tasteful.
