Gucci Ambassador and Gossip Girl alum Blake Lively and her husband Ryan Reynolds made a rare public appearance at Gucci's Chime for Change Concert in London this past weekend. Blake looked absolutely phenomenal in a white Gucci dress from their Spring collection. She then accessorized with a ton of colorful Lorraine Schwartz bangles and drop earrings. Last, but not least she wore Christian Louboutin heels. Ryan looked pretty dapper too. Blake introduced her "good friend" Florence Welch from Florence + The Machine, because ya know, they're BFF's. What do y'all think of Blake's outfit?
