Parties! The style, stars and scoop from Hollywood's hottest events

It was an ironic iconic evening under the stars when In Style joined forces with Tommy Hilfiger to celebrate the designer's new Bravo special, Ironic Iconic America. "Tommy Hilfiger is America!" declared Emmy Rossum (in Lagerfeld Gallery), who joined fellow guests Jenna Fischer and Elizabeth Banks high above Beverly Hills on the rooftop of the Thompson Hotel for the soiree.
