Bebe Purple Silk Sheer Black Cutout Open Back Cocktail Dress Sz XS

This dress is practically vintage at this point! I can't seem to find it online, other than through one other Posher... I bought it maybe 10 years ago from a cool used clothes store and I've probably worn it twice since, but I also didn't have the heart to sell it before because it's gorgeous and is very flattering and sexy... but I don't have many fancy things to go to and it's a waste just hanging there! Please note the black sheer is running a bit (see last few pics*) I'm not sure if you find it noticeable you may want to have it replaced. Also, there is a small mark in the lower front (see last few pics*) I'm not sure what this is or if it will come out, but may not be noticeable to you. This is why I have it priced so low, it's a very beautiful dress! Size XS
