This is a St. John Evening by Marie Gray black knit evening dress . I wore it only once for a few hours thus it is in perfect condition. I had bra cup added to the bust tfore you don't have to worry about wearing a bra as the back is lower cut. ( So popular right now - see the latest issue of Vogue).T are two adornments on the back straps (each is missing a stone but is barely noticable). This dress is a size 6 but would fit a size 4 or a small 8 as the dress is made from a stretchable knit fabric. Any questions please ask. Check out my other items. Thank you. Payment is due within 5 days of auction end.
