Apart from the weird and wonderful on-stage costumes on show at the Billboard Music Awards, there was also a more subdued trend going today. Black was the hue du jour, making for an elegant line up of frocks on the white carpet. What could have turned in a snooze-fest was kept interesting by these ladies' keen eye for detail. Despite being black each dress had its unique point of interest; be it via a bejewelled neckline like Beyoncé's Lanvin LBD, sexy cut-outs as seen on Selena, peek-a-boo fabrication c/o Kylie's LBD, beautifully beaded as picked by Nic, or feather-skirted like Michelle's. See what we mean? We're usually a sucker for colour, but this stylish line up reminded us how elegant (and versatile) the trusty black dress can be.
