Rihanna showcased her singing voice for the live finale of The Voice. She wore a Lanvin tuxedo jumpsuit from the Parisian spring/summer 2013 collection, covered entirely in embroidered Swarovski crystals. Ri-ri has been making some savvy style choices of late, stepping on stage in Azzedine Alaia and Alexander Wang. Lanvin seldom fails to impress style insiders; the Parisian house has been bought back to the forefront of the fashion press since Moroccan-born Israeli fashion designer Alber Elbaz took the reins in 2001.
