The Best Dressed at the 2009 MTV Movie Awards

Sienna Miller earned best dressed last night, in a fabulous long-sleeved Swarovski-encrusted, emerald green Twenty8Twelve mini dress with strong shgoulders. Accessorizing with a silvery clutch and high-stepping Nicholas Kirkwood heels, the British Actress' casual glamour played well to the casual, hip vibe of the MTV Movie Awards.(Photo: WENN)
