At the Who What Wear 50 Style Stars event held yesterday in West Hollywood, the fashion designer decided to shake things up, showing up in an early Halloween costume. Richie looked like Catwoman from the Gatsby era, wearing a delicate lace veil with cat ears perched on top of her head, a sequin-and-fringe dress with plunging neckline, and leather leggings. She held on to a cream clutch for contrast and, we're guessing, spent the rest of the night dancing the Charleston in her stilettos. Choupette would be proud.
