To mark the 10th anniversary of Pink Pony, Polo Ralph Lauren is holding its First Pink Pony Online Auction in partnership with luxury charity auction site, charitybuzz, to benefit cancer research. With one-of-a-kind denim worn and signed by Tom Cruise, a patchwork American flag handcrafted from recycled vintage denim, jeans signed by Ralph Lauren himself and many more Ralph Lauren denim looks up for auction. 100% of net proceeds will be benefiting The Pink Pony Fund for cancer research. The auctions run until 21st October 2010. I think the best auction is definitely Tom Cruise’s jeans he wore on Knight and Day! Check out all of the auctions by clicking here.
