Check out how Rihanna paired her Stella confection with a funky hemline dress, while the designer herself chose to wear hers with a slick purple frock from the same collection. Gossip Girl Blake Lively was most recently spotted donning Stella's rad boots with a basic white shirt and blazer. Three beautiful ladies, three totally different looks, which one do you prefer?
