Looks like the fact that her label Twenty8Twelve's London Fashion Week debut is just around the corner hasn't affected Sienna Miller one little jot. Attending the Mont Blanc ‘Signature for Good' UNICEF Charity Gala in Los Angeles on Friday, the actress schmoozed with the likes of Susan Sarandon, Eva Longoria Parker and Emily Blunt just two days before her show in London this evening. Whereas most designers would be spending sleepless nights pacing their studios in the run up to the shows, Miss Miller seems pretty laid back by our standards. Last time we caught up with the Miller sisters, the collection was sounding pretty hot with its highwaymen inspired Victoriana and padded shoulders, so maybe Sienna's just feeling chillaxed about it being all so under control. OR perhaps she'll ditch LFW all together and stay put across the pond in order to attend the Oscars tonight... Oh decisions, decisions! Either way, we'll be bringing you the latest Miller update so check back here v soon.
