Designers paying models in clothing is an age-old practice, as is models helping themselves to an accessory or two at the end of a show—whether they're invited to or not. Such was the case with one sticky-fingered girl backstage at YSL last week, who gave herself away when we spotted a very familiar-looking black patent-leather platform Mary Jane on the end of her very familiar leg last night. We're too polite to name names, but if Stefano Pilati is reading this, we'd be happy to lead him to his missing footwear.
