Back in 2008 Rihanna rocked out at a private concert wearing a hot pink dress by Betsey Johnson. The dress is from the Spring/Summer 2008 collection, which was based on prom. Rih’s dress is called the Dahlia and features a sweetheart neckline and a tiered skirt. Each tier is edged in black sequins and underneath a bit of black tulle adds edgy flirtiness. Don’t you just love the pop of turquoise on her nails?
