Last week a pregnant Rebecca Romijn was the guest judge on Lifetime’s “Project Runway”, as the designers had to create stylish maternity wear. The week before in the premiere show, Lindsay Lohan judged red carpet gowns.

On last nights show Rachel Bilson was the guest judge.

The actress looked super cute wearing a white ruffled blouse, a black skirt and snazzy, patterned Chanel Fall 2008 tights.

You may remember in this collection the tights were uniquely half patterned/half opaque.

I’m impressed that Rachel has kept a pair of tights that long, most of us only wear them once before they ladder.
