Stars like Jessica Alba, Jessica Biel, Zoe Saldana, and our favorite stylist Rachel Zoe hit the Rodeo Drive Prada boutique to celebrate the brand’s first-ever retrospective book, Prada—and its 706 pages-worth of fashionable moments! We caught up with Zoe at the party to find out her personal favorites from Prada’s chic history. “What don’t I love about Prada?” said Zoe. “Miuccia breaks all the fashion rules and that’s why people buy it. I have to tell you her collection…of all the bras and corsets—that was incredible.”

Michelle Obama proved her style savvy once again by re-wearing the same J. Crew skirt, top and cardigan ensemble she wore last fall on the Tonight Show with Jay Leno to a health care event last week at the White House. She used her keen taste in accessories to give the versatile separates a fresh spin by trading the cardigan’s brooch for her new favorite piece, a waist-cinching laser-cut belt. An old outfit gets an entirely new look in an instant!
