Rachel Bilson to Matthew Williamson: Milan Support!

Rachel Bilson supports designer Matthew Williamson at the show for his Spring/Summer 2011 collection on Sunday (September 26) during Fashion Week in Milan, Italy.

The 29-year-old actress made her way through the airport in Los Angeles on Saturday en route to Milan in a pair of rainbow socks!

Rachel spent some time earlier this weekend at the Christian Dior boutique in Beverly Hills, Calif. She must have been stocking up on some new styles for Fashion Week!
