This is a former rent the rent way dress by Sachin and Babi. It is size six. It is strapless with back zipper and boning on back to keep firm. The top around the back and bust has a rubber strip to keep it clinging to you so no slippage. No bra cups, but thick fabric forming molded bust. I stitched the bra area to keep the front points in place. Poof hem is supported by fully lined dress. Gathering around the waistband. What a great way to wear an eye popping designer dress sold for $495!!
