Dresses were having a major week — and the women who wore them didn't look half bad either! Blake Lively was a style standout in her lacy Marchesa look at a New York Van Cleef & Arpels bash, and hers was among the most subdued of the week's looks. Bright colors ruled the day for Claire Danes in Valentino, Julia Roberts in Proenza Schouler, and Kate Mara in J. Mendel. Click through to see the looks we loved on some very chic ladies.
