Kate Hudson layered up in a leather-sleeved Helmut Lang coat while attending a special Muse concert for the War Child charity in London last night. The actress, who was there supporting her fiancé and Muse frontman, Matt Bellamy, wore a silky green jumpsuit underneath, then finished with a pair of cozy shearling Burberry booties.Zoom in on Kate's beautiful accessories: green chandelier earrings, a prominent knuckle ring, and this Stella McCartney python crossbody bag ($1,200), which Anne Hathaway also owns. While we admire Kate's layering chops, it was her accessories that really amped things up. We especially admire the pop of green via her earrings. Score her exact bag and similar jewels to jazz up your Winter wardrobe à la Kate Hudson.
