Nicole Richie has been busy in NYC promoting her Fall '10 Winter Kate collection. For her in-store appearance at Bloomingdale's, the newly engaged celebrity designer shed her Winter coat to show off her California cool style — a pair of denim cutoffs, white collarless shirt, and a cute black Winter Kate crochet vest. Opaque tights, suede Christian Louboutin booties, and stunning engagement ring complete her funky boho look.
