Actress Rachel Bilson and actress Kristen Bell looked fabulous as they attended “Dinner with a Designer” hosted by InStyle and the Council of Fashion Designers of America, celebrating Brian Atwood at Soho House in California this week.

Keeping her hair pretty much the same as always, Rachel opted for a Peter Som Fall 2010 strapless floral dress with a black velvet band and a frill around the waist.

I love the look which she paired with Brian Atwood heels and a woven taupe Ferragamo clutch.

Kristen Bell’s look was more summery despite it being from the Stella McCartney Fall 2010 collection.

She wore a strapless dress with a sequined skirt and an organza layer.

Her look was colour coordinated with Brian Atwood Katie Lee patent-leather sandals.

Both look so good, I don’t know which one I like the best.
