Size 38. I bought this item on Poshmark for a couple hundred under full price and was told it was unworn! I have worn it once for an engagement shoot and cleaned it, however when I received it it had two small holes under the armpit, which have since spread into a larger hole, as pictured. Not noticeable on but it is there! I included a video of it. Price reflects this. It has had a bustle added as well, as pictured. Sizing is not altered at all. Size 38 on Rime Arodaky’s website in inches is bust: 36 waist: 28.5 hips: 40.5. It is tight with no stretch.
