The Diane Von Furstenberg sample sale opened to the public this morning, and, like the last one, it's mayhem. If you brave the madness, this blogger advises you to head straight to the samples in the back, which are going for $40. Aside from those, sweaters are $70, dresses and jackets are $100, and other merchandise is significantly reduced. And play nice in the dressing rooms — the staff is yelling at shoppers in there, threatening to impose a ten-minute time limit. [Racked]
