What do you wear when you're invited to a dinner to celebrate the debut of celebrity stylist Rachel Zoe's namesake collection? An outfit designed by Zoe, natch!

InStyle magazine hosted a party for the proud new mom, 39, (she brought her infant son Skyler Morrison Berman and husband Rodger Berman to the soiree) and her A-list pals at the Soho House in West Hollywood, California on Tuesday night.

Beau Garrett, 28, wore Zoe's black and white print minidress with Stuart Weitzman shoes and a vintage bag. "I picked this because I thought it was kind of punk rock and cool," she told InStyle. "And it's comfortable!"

Ali Larter, 34, (who gave birth to son Teddy in December) paired an ivory blouse from the Rachel Zoe Collection with Alexander Wang shorts, and Chanel purse and Rachel Zoe boots.

So You Think You Can Dance host, Cat Deeley, 34, sported a white sleeveless vest and mini designed by Zoe with Christian Louboutin heels and a vintage bag.

And what did the guest of honor wear? A one-shoulder gold ruffled dress from her Rachel Zoe Collection.

"It's one of my faves," she told InStyle. "I actually wore it throughout my pregnancy and I'm wearing it tonight because I have to be up and hosting. I just want to be comfortable, but glamorous."
