The former The O.C. star launched her own clothing line, Edie Rose, with DKNY Jeans last year (08).
However, Bilson admits she still studies the looks of other starlets before stepping out on the red carpet.
She tells People.com, "I really look up to a lot of my peers and how they dress. I love to admire other people. Ashley Olsen I think is great, Diane Kruger, Sienna Miller - all those people obviously have good style, so it's nice to see that around you. Your peers surround
you, and they all look good, so that's great."
