Costumes worn by Julie Andrews and members of The Sound of Music's child cast are to be auctioned in Hollywood later in July.
The movie star's Maria dress, which Andrews wore while performing Do-Re-Mi in the film, and the outfits her singing governess character handmade for the Von Trapp children from draperies, will be among the highlights at the Profiles in History sale on July 29.
"Without question, this is the most comprehensive collection of signature costumes from The Sound of Music any institution or collector could ever hope too obtain," a spokesman for the auction house told WENN.
"Included with the costumes is a four-page typewritten story of the Von Trapp family signed by Maria Von Trapp, explaining the origins of the singing family and events leading to their eventual escape from Third Reich-controlled Austria.
"The clothing collection is estimated to fetch up to $US1.2 million ($A1.33 million).
Andrews recently shared her personal stories with Australian audiences with her show An Evening With Julie Andrews, which toured the country in May.
