The 26-year-old singer arrived at the stylish event, held by the Council of Fashion Designers of America, in a floor-length sparkling gown that recalled the era of Josephine Baker.Custom-made by designer Adam Selman, the mostly backless number shone from more than 230,000 Swarovski crystals and was accented with a baby pink feather boa, gloves and a glittering turban.But it wasn't just Rihanna's effortless 1920s glamour that turned heads. As Selman described to Style.com, "the dress is just fishnet and crystals and a couple of fingers crossed." That left everything that wasn't covered by a flesh-colored thong on full display."It's so naked," Rihanna's stylist, Mel Ottenberg, added to Style.com. "I don't know if it's shocking -- I'm with her all the time, so my shock gauge is off -- but I told her that I thought she was ready for this dress a while ago, and that I wasn't. I'm the prude, and I'm just catching up."Ottenberg may still be getting used to the revealing look, but some observers -- like fashion magazine Vogue -- have heartily approved."Fashion should never be frustrating," Rihanna said during her acceptance speech. "It should be fun."(CNN)Bakudaily.az
