Watching it today I was struck by how beautiful and chic Deborah Kerr is in this film. She was 36 when it was released and she appears womanly, sophisticated and radiant. Her costumes are all kinds of late 50s gorgeousness - the beige and orange evening gown at top and the orange opera coat at bottom are faves - and a little bit of detective work led me to Hollywood costume designer and wardrobe director Charles Le Maire.
Charles Le Maire won four Oscars for his work in costumes and was responsible for the looks on memorable classics like Three Coins in a Fountain, How to Marry a Millionaire (who can forget the famous fashion modelling scene?) and The Long Hot Summer. Although when it comes to the latter, I think putting Paul Newman in virtually nothing at all was just about the best costuming decision made.
