Rihanna  takes center stage on the March cover of Vogue, the fashion bible's second biggest edition of the year after its all-important September issue. So it makes sense that in the issue she wears everything from Saint Laurent  to Alexander Wang  to Maison Martin Margiela .
It's her third time covering the magazine, following April 2011 and November 2012. But it's not the only glossy front we're obsessing over this month. Scroll down to see the stunning covers of Teen Vogue, W, Harper's Bazaar, and more.
