BCBG black cocktail dress

Black cocktail dress, sexy ruched bodycon style with an open back - the shoulder fall open really beautifully but are held in place by the strap across the back of the neck. Material is soft and stretchy, and the dress is definitely versatile. Lots of different shoe options to work with it, and I wore this a few times with my leather jacket. I’m actually not sure if it’s a size 4 or 6 I can’t find the tag - I fluctuate between sizes typically, so I imagine it fits either.
