For more casual chic, you can bid on Evangeline Lilly's 'Kate' costume from season 1 of ABC's 'Lost'. This and tons of other cast outfits are on auction for the next few days. (My personal favorite in this auction is Hurley's Mr. Cluck costume).
Clothes Off Our Back is an organization founded by "Malcolm In The Middle" star Jane Kaczmarek and actor Bradley Whitford from "The West Wing". It takes clothing and accessories worn by celebrities to auction off to benefit children's charities. Currently, you can bid on a necklace worn by Lindsay Price from the "Lipstick Jungle" and garments directly out of Bette Midler's closet.
