"It was the first thing that sold off the shelf," Ashley, 25, said at the Paris launch of their new handbag collection Sept. 30. "During our last economic crisis in the U.S., the only thing that went up was Hermes."

"If you were ever going to spend $39,000 on a bag, that's the bag you should buy," she told Fashionista in July. "There's enough design to make it interesting and beautiful but they truly are classic bags -- and I think you also might be the only one who has it."
