The tag says size 34 (equivalent to a US size 2) but I think I may have shrunk the dress in the wash. I mostly noticed a difference in the length (pictures included for reference, I am 5'7") so if you are shorter or just prefer dresses on the shorter size I think it would still work. Please see the measurements provided below. Some of the loops that hold the buttons are slightly stretched as well as shown in 8th photo. Otherwise the item is in nice pre-owned condition. All offers are appreciated! Measurements: Pit to pit: approx. 16.5" across Waist: approx. 13.75" across Length: approx. 32" shoulder to hem
