Not every Hollywood party requires dressing up, as proven by the bash Lucky magazine threw last night with Madewell at Bar Marmont. Rachel Bilson, Joy Bryant, Kristen Bell, Rashida Jones, Jessica Capshaw, Anna Faris and Kat Dennings were among the starlets who showed up to sample the wares, make photo flip books and have their fortunes read by Bilson's mom, Janice. "I like to tell people I too am insightful, but I don't know the ways of the tarot cards," said Rachel. The starlet did, however, have fashion wisdom to impart: "I think it's great to mix and match pieces and create your own look," she said of her Madewell top and Myne skirt.

Nearly everyone else followed suit, pairing basics with vintage and designer pieces. "In L.A. you usually can't dress like this for a red carpet," said Jessica Capshaw, in a Madewell mini and ALC jacket.

But there was one place where Faris drew the line. "Don't think I have the guts to wear the boyfriend jean."
