Vinateg butterfly 60s dress

vintage butterfly dress 🦋🌸. real vintage. No size or tag, but I'm guessing m-l depending of measurements. Im usually a size l in dresses like this, and my rib cage is too big for this dress, but it fits everywhere else. really cute and lightweight. Dm for measurements :) Ptp- 17 3/4 Small part of waist- 17 1/2 Length from shoulder- 40 #70s #60s #vintage #summer
