Blake Lively turns 27 on August 25th, 2014 and one of the reasons why we love her so much is the fact that she doesn't have a stylist. That's right, the "Gossip Girl" star goes it alone, choosing her own looks for the red carpet (granted, she's admitted that if she's stumped on shoes she'll just text her friend Christian Louboutin for advice! No big deal...).
So in honor of Blake's 27th birthday, we collected our favorite looks she's worn over the last few years. Click through the gallery to see!
