Ruffles can be a tricky trend, and less is definitely more with these bouncy, fluttering fabrics. Rihanna has a long history of wearing ruffled clothing -- good and bad -- on the red carpet. The yellow Giambattista Valli maxi dress she wore to the 2008 BET Awards would've been better suited for Little Bo Peep than the provocative star. Not only were the layers of ruffles too busy and distracting, the frock was too juvenile for Rihanna, then 20 years old. However, the Viktor & Rolf ruffled dress she wore to the Recording Academy's 2010 GRAMMY Salute to Icons Honoring Clive Davis was widely praised by fashion critics. The singer shined in the geometric dress, featuring dramatically-shaped ruffles made of tulle in soft pastels.
