Beyoncé is among the celebrities who have donated clothes to be sold at a new charity shop in London

, which sells gowns and other high-end clothes.

The store, which is being called “Britain’s biggest charity pop-up shop,” is the brain-child of singer [lastfm]Annie Lennox[/lastfm] British TV personality Zoe Ball and R&B star [lastfm]Beverley Knight[/lastfm]. Besides [lastfm]Beyoncé[/lastfm], other celebrities that have donated one-off dresses include model Elle Macpherson, actress Helen Mirren and Stella McCartney, [lastfm]Paul McCartney[/lastfm]‘s fashion designer daughter.

The store opened its doors this week and will close on May 20. The money raised will be used to help Oxfam women’s projects.
