Dress costing £3.5million unveiled in Ukraine One of the world's most expensive dresses has sparkled on the catwalk at a fashion show in Ukraine . The dress, created by British designer Debbie Wingham, is adorned with 50 two carat black diamonds, and weighs 29lb (13kg). Presented at a show featuring several other diamond-encrusted dresses from Ms Wingham's collection, the black diamond dress received a mixed response from the audience in Kiev. One visitor complimented the dress on how good it looked both on camera and in real life. "It really emphasises the star quality of the person who wears it," she said. Others were not so enamoured with the dress. I don't even want to try this dress, either to show it off, or to have pictures taken. I regret that so many diamonds were 'killed' by such an ugly-looking dress," said one glamorously dressed lady attending the show. The dress is valued at £3.5million pounds.
