Rachel Bilson: Amber Valletta for Monrow!

Rachel Bilson comes out to support actress pal Amber Valletta at the launch party for the new Amber Valletta for Monrow collection at Ron Herman Melrose store on Thursday (November 19) in Los Angeles.

Of course, the 28-year-old actress wore an Amber Valletta for Monrow creation — a cream pleated 50′s dress.

Earlier in the day, Rachel was seen stopping in at the Four Seasons Hotel for a business meeting before heading to her mother’s home in The Valley.
