If you've ever dreamed of dressing like Dwyane Wade, your chance is here.
You can win a pair of the Miami Heat star's pants and donate to a charitable cause in the process.
Blue Jeans Go Green is auctioning off a pair of jeans autographed by Wade.
But the person who wins isn't the one who is willing to spend the most, it will be whatever person can collect the most denim to be recycled, in order to be redistributed to communities in need.
People who want to participate in the The Great Denim Challenge should collect as many denim items as they can. The number of items collected will determine how much "denim currency" a person has. "Denim currency" can be used to bid on apparel autographed by different celebrities.
The highest bidder in each auction will be contacted by the organization about how to claim his or her prize. The challenge closes November 3.

Other participating celebrities include Andy Roddick, Britney Spears, Hayden Panettiere, Kourtney Kardashian, and Ryan Phillippe.
