Back home after a trip to Milan, Rachel Bilson was spotted out supporting her pal in Beverly Hills on Thursday (October 1).

The former "OC" actress made her way over to the local Neiman Marcus, attending the Brian Reyes appearance as her designer friend promoted his latest offerings.

Known for her stylish ways, Miss Bilson happens to be the covergirl for this month's Lucky magazine - in which she talks about her always-evolving fashion.

The 28-year-old tells: "I'm constantly trying new things and experimenting, so I never really settle on one style. By the time I figure out how to define my look, I'm usually ready to move on to something else."
