The singer definitely has a signature style when it comes to hitting the red carpet. Black floor-length gowns with three-quarter sleeves are her go-to frocks, and she loves to volumize her hair for a little extra va-va-voom. She stunned in a black Burberry dress with a sheer neckline and sleeves at the 2012 Brit Awards and wore a similarly shaped glittery Georgio Armani dress to the 2012 Grammys.
