My favourite dress of all time was made by Mia Fonssagrives and Vicky Tiel in 1965 for Paula Prentiss to wear in Woody Allens 'What's New Pussycat' which I went to see 5 times the week it opened. The dress is backless, which is not apparent from this picture of it worn by Jane Holzer for VOGUE USA. The Mia and Vicky label however, was backed, and by none other than Dame Elizabeth Taylor, and Mia was the daughter of a legendary 50's model Lisa Fonssagrives - Erwin Blumenfeld photographed her famously, in a long gown and swinging by one hand from high on the Eiffel Tower. What's New Pussycat, was of course, set in Paris, and if you follow that link there is a photo of Paula in the movie version of this fab frock.
