Sienna Miller Steps Out In Style With Pal Matthew Williamson

Sienna Miller wore an adorable Grecian goddess dress at a party for Belvedere Vodka Pink Grapefruit yesterday. No surprise that her frock was designed by none other than her date, designer Matthew Williamson who was also playing host for the star-studded affair.

The British starlet appeared to have a little bit of a makeover, with bold red lips and severe bangs. But the fashionable actress looked stunning as always, and it never hurts to have a fashionable man as your arm candy…right Jude?
