Carey Mulligan is selling her Met Ball dress on eBay.
The 26-year-old actress - who was accompanied the annual Costume Institute Gala on Monday (07.05.12) by her new husband Marcus Mumford - is auctioning the custom-made gold and silver Prada gown for charity, with proceeds going to Oxfam.
The gown was put onto the website on Wednesday (09.05.12) and bidding runs until May 19, with the current highest bid standing at $1,025.
The listing describes the dress as a ''piece of fashion history''.
It reads: ''You can bid on Mulligan's custom Prada gold and silver degradé metal paillettes scaled halter neck dress. This dress has been photographed by most news outlets, from the Chicago Tribune to NY Magazine, Vogue and Style.com, and has generated significant media attention. A true piece of fashion history!
''Custom dress sized between 38-40.''
This is not the first time Carey has sold one of her dresses to raise money for Oxfam.
In May 2010, she donated the Vionnet dress she wore to that year's BAFTA Awards to raise money for the charity's women's projects.
She said at the time: ''I'm honoured to be able to donate my Bafta dress to support Oxfam's work helping women living in extreme poverty across the world.''
