If there's one hair trend that turned our heads at the Spring/Summer '11 shows, it was the stylists' penchant for big hair. And it wasn't all about a bouncy blow-dry as in previous seasons - this time spiral curls, tiny ringlets and big cloud shapes were on the agenda, and we even saw a little - intentional - frizz. Never one to ignore a hair trend, Rihanna has embraced the look wholeheartedly, seen here arriving at Las Palmas nightclub in California. Us ELLE girls love a lady who goes for it with a seemingly tricky trend - look out for a forthcoming issue where we'll share a how-to on how to work this look at home.
