Black lace, deep v, two sexy slits dress

I think the size is a Medium. I don't remember and the tag does not say. I'm 5'7, 150lbs, b cup. The top is a bit big on me but that can be adjusted with the straps. Even when wearing 4 inch heels the dress is a nice long length. The slits come all the way up to the waist band, so it's very sexy
