New mom Kristin Cavallari treated herself to the hair salon in Beverly Hills wearing a slimming black and white ensemble. Up top she sported this Elizabeth and James white peplum top ($285) and on bottom black skinny jeans. For her accessories, Kristin chose black Christian Louboutin pumps, black Ray-Ban Wayfarers, a silver watch, and the mega statement piece, a gray Hermès tote. Score Kristin's exact white peplum top to wear with jeans during the day, a pencil skirt at work, and then with leather leggings for an edgy-slash-chic night out.
