Authentic BCBG Cocktail Dress size 4

This is a gorgeous BCBG dress that I bought to wear to a friends wedding. It is a size 4, but I lost a lot of weight by the wedding time, so it looks alittle big on me. It's a very well made dress, thick and great bust support. I got soo many compliments even though it was not super tight on me. (I am now a size 2) this runs true to size, 4. In perfect condition and has been dry cleaned. Thx!
