Victoria's Secret Red Slip Lingerie Valentine Christmas backless halter lace

Victoria's Secret slip mini dress, purchased around 2012, worn once to a party (not during intimate times). Beautiful bright red, NOT orange-red. Elastic at back, hook closure and adjustment at halter strap. Very cute and slightly demure (purchased for a lingerie party by someone who is tummy-conscious.) I believe it's polyester, but I don't know for sure. Ask me any questions you have! Make me an offer!
