Blake Lively [1] was all dressed up on The Tonight Show Starring Jimmy Fallon [2]. The actress is on a whirlwind press tour promoting her new movie All I See Is You [3], and for the talk show appearance, she wore a one-shouldered lavender gown. The Roland Mouret dress featured a sweetheart bustier and soft, pleated hem that flowed when Blake walked.
It's been a while since we've seen the star, and she looked radiant as ever in her ensemble. In fact, we think her Gossip Girl [4] alter ego Serena van der Woodsen would likely approve of this purple dress. Blake topped off her designer look with jewels from Lorraine Schwartz and a sparkly pair of Christian Louboutin pumps. Read on to see her full outfit, then shop similar dresses ahead.
