I’m basing the size completely and measurements because well I know I ordered a size large. This is not labeled that I can find anywhere and it is absolutely not a size large. This measures about 16 1/2 inches across pit to pit and about 11 inches across at the completed elastic shirred waist. I would say this would comfortably fit a size 8 or smaller. Maybe a size 10 if you are a 36c or smaller. When I purchased this, I was a size 10, 34 double D and it was too small. This is advertised on their website as a silk dress, but it is a silk viscose blend. It is a beautiful sage, smoky color. And it has voluminous teirs. It’s a gorgeous dress and one similar to those at free people or Anthropologie. I would say this is closer to the midaxi range. It comes about 3 inches above my ankle on my 5 foot seven frame. Just shy of being a full maxi and too long for a Midi. Easily worn with flats or sandals. Would make a beautiful wedding guest dress or bridal shower dress.
