Teal Drop Waist Peacocks Dress

Bought this secondhand while I was in Wales two years ago. Didn't try it on at the time and now I dislike the cut on me. UK brand so the size 12 might be a bit smaller than usual. However it does have a TON of stretch to it. Armpit to armpit: approx. 17in Length (shoulder to bottom): 34 1/2in
