Topshop evening gown/prom dress WITH TAGS

Black silky topshop evening gown. I bought this in new york for my schools prom and lost the receipt so it cannot be returned. Only worn in the dressing room and at my house, no alterations done. Its a beautiful gown and has a slit up the left side. Nothing wrong with it i simply found a different dress to wear. It has nice stitching in the front. I can facebook message you more photos if needed. US 6 UK 10
