Sienna Miller Makes It to Matthew Williamson

Sienna Miller sits front row at the Matthew Williamson Spring/Summer 2011 presentation at the Battersea Power Station on Sunday (September 19) in London, England.

The 28-year-old actress and designer has been busy during London Fashion Week. The day before, she and sister Savannah showed off the latest collection from their Twenty8Twelve label.

At the Matthew Williamson show, Sienna sat next to and chatted with British model Poppy Delevigne. “I thought it was beautiful,” Sienna told reporters after the show about her long-time friend’s fashion show. “The dresses were stunning.”

FYI: Si is wearing the cute Beatrix Ong “Oru” shoes, Seven jeans, Acne top, Helmut Lang jacket, and Geminola necklace. She finished off her accessories with a plastic bracelet with her name on it that was made by her and the Twenty8Twelve team!
