This is a very sought after nicole miller dress seen on Nina donrev in the vampire diaries, as seen in the mortal instruments movie on clary fray ( slightly altered in movie, and is a very hard size to find! I got this new and finally wore it once- it’s time she moves on to the next lovely lady who’s wanted this perfect cocktail style LBD! Size M ( it does stretch! Easily a size 8-12( depending on the brand) if it helps I wear a 34dd -29”waist-41” hops and it fits just fine!
