Free people ruby red halter dress mini runs 4-6 cocktail evening party night out

Free people wish upon a star mini dress with black lace overlay and rhinestones. Actual size is 2 but runs big. I wore it when I was size 4 and now that I am size 6 the dress still fits, as long as you don't have wide waist. I bought it preowned from someone else for event and wore once, in great condition. Only thing is I find FP designed awkward underarms cut that creates big gap and might need pinning, is why I will leave my pins for the buyer just incase.
