Bridesmaid dress

EUC Jessica McClintock bridesmaid dress in Gus chia pink. Very simple and classic. Tea length. Has internal “bones” to help give structure to bodice. Runs small. Modeled on 5’5, small/size 4. It is larger in the model but doesn’t look like it. Reference measurements as well, laid flat: length-34”, waist-15. Would most likely fit a medium/6-8 best though it is marked size 12.
