Simons has much support in the industry. His designs have increasingly becoming a bellwether for trends. Lately, his clothes gained support in fashion magazines, and the Jil Sander show became a must-have ticket during the Milan Fashion Week.
Still, he doesn't have the celebrity of a Galliano, and Jil Sander didn't have as broad an audience to please as does Dior. It will be the trick for Simons to balance exciting, fashion-forward design with global appeal that will find its place on red carpets and in department stores.
