The velvet green gown donned by Vivien Leigh in 1939 epic Gone With The Wind will be the star piece in the Hollywood Costume exhibition at the Victoria & Albert museum in the British capital.
The gingham dress worn by Judy Garland in the Wizard of Oz is being loaned to the show by a private collector and will be displayed alongside a pair of ruby slippers the actress wore as Dorothy in the 1939 musical.
Organisers are also including outfits from more recent films, including a cloak worn by Johnny Depp in the Pirates of the Caribbean franchise and Christopher Reeve's Superman get-up.
Co-curator Sir Christopher Frayling says, "There has long been a tendency not to consider movies a proper art form. Also previous exhibitions from years ago about movie costumes made them look like static wax works."
The exhibition, set to open in autumn (12), will also feature movie clips and interviews with stars including Meryl Streep and Robert De Niro.
