The auction is going live on eBay tonight at 7pm and will help raise funds for the Lavender Trust charity- a group supporting women suffering with breast cancer. All the dresses will be sold on eBay at three-day intervals until the release of the film.

Many of the donations are well known red carpet dresses, and straight off the backs of people like Mariah Carey, Geri Halliwell, Thandie Newton, Naomi Campbell and Heidi Klum. 

Obviously, the auction comes just in time for the release of Katherine Heigl’s latest film, 27 Dresses, which will hit nationwide March 27th (insert obvious plug here). 

So if you just gotta, gotta, gotta dress like a star and want to help a super neat charity, visit the 27 Dresses Celebrity Dress Auction homepage and find out more.
