What is it that we love about Rihanna? Namely, her style. 

Like with her music, the singer harmonizes extremes in a magnificently dazzling fashion performance, which is why she lands at No. 1 in InStyle's first-ever roundup of the 50 Best Dressed Women in HollywoodFrom her pink Giambattista Valli confection at the Grammy Awards (the designer said, "She wears couture like a T-shirt") to her many ground-breaking Dior looks, Rihanna's look is always outrageously brazen and yet impeccably stylish. So it should come as no surprise then that her personal style empire contineus to grow. In addition to developing her own line, she's also Puma's women's creative director.
