The listed size is XS, but I feel it's equivalent to a size 7 (US 3/4). (I tried on a size S, but the armholes were too large and it looked like my undergarments would show, so I chose XS.) I've worn it about 5 times, but because it's 100% silk and a soft material, there are several areas with pulls, as shown in the photos. The thread on the hook at the collar is frayed, but I will sell it as is. Dry cleaned by Hakuyosha. Length: Approximately 110cm, Waist (elastic): Approximately 32cm
