Rachel Bilson and Emmy Rossum Pictures at TCA Party

Last night, CW, CBS, and Showtime hosted a Summer TCA party in Beverly Hills attended by a bevy of Hollywood beauties. Rachel Bilson made an appearance in red-hot Erdem separates, Jamie King opted for a semi-sheer lace set from Valentino, and Claire Danes colorblocked in a nude and red dress from Reed Krakoff. Kristen Bell and Emmy Rossum also caught our eye in Versus and Etro, respectively. Each look is beyond inspiring, but which one is your fave? Flip the slideshow to see all of their looks, then vote on the number one stunner.
