Who designed the dresses in Auntie Mame

An Austrailian-born costume designer whose professional name was Orrly-Kelly designed the costumes for Morton De Costa's 1958 film adaptation Auntie Mame. Originally coming to the U.S. to become an actor, he instead found fame as a three-time Academy Award winner for Costume Design. Orry-Kelly won Oscars for:

• An American in Paris (1951)
• Les Girls (1957)
• Some Like it Hot (1959)

He was nominated, but did not win an Academy Award for Gypsy. He was a proflic designer having worked on well over 275 Hollywood movies. His brilliant designs appeared in many famous movies. Some of my favorite costumes in Auntie Mame are the copper-colored jeweled pantsuit with matching asymetrical silk long walking-coat, and the crystal studded capri-pants outfit and chartreuse shawl that Mame wears to her dinner party designed to rid Patrick of the Upson's once and for all. His costume designs were genius.
