Rachel Bilson: Bright Red Short Shorts!

Rachel Bilson goes shopping with a friend at a furniture boutique on Monday (July 18) in Santa Monica, Calif.

The 29-year-old actress paired a black blazer and white tee with bright red shorts and ankle booties.

Rachel has been busy filming the upcoming comedy, The To Do List, which centers around a high-school grad who feels pressured to become more sexually experienced before attending college.

Last week, Rachel walked around the film’s set in a pink robe and a few days later wore a blue one.
