Gowns Madonna wore for her Material Girl video and as Evita Peron in Evita are to be auctioned off as part of the singer's biggest memorabilia sale.

Julien's Auctions in Beverly Hills are handling the items, which will be going under the hammer as part of an upcoming Icons and Idols event in November (14).

Alongside the two signature dresses, over 30 costumes and accessories from Madonna's life onstage and onscreen will be up for sale at what is being billed "the largest collection of Madonna memorabilia from her personal and professional life ever to be offered at auction".

The sale will also feature the outfits from the singer/actress' films A League of Their Own and The Next Best Thing and from the videos for Music and American Pie.
