One of the provocations of the 60's was when Yves Saint Laurent (1936- 2008) designed pantsuit for his pret-a-porter collection Rive Gauche in 1966.
However, the first pantsuit was designed even earlier, in the beginning of the 60's in London by Sally Tuffin and Marion Foald (dress on the picture below). That pantsuit was designed as a rebel joke against establishement and the women who wore it were not allowed to enter to many places in London, Paris and New York.
In 1967, Yves Saint Laurent designed famous ''le smoking'' for women
This pantsuit which include three parts of clothes was designed in 1968 by Tommy Nutter, who opened a saloon in this year on Savile Row. He became very prestigious and made pantsuits for Mick and Bianca Jagger.
Jane Birkin (*1946) had her first important role in her second film- Blow up in 1966, then she came to France, where she brought her cool style and where she got a role in Slogan. There she met Serge Gainsbourg, with whom she lived for thirteen years and with whom she had daughter Charlotte (also an actress)
Twiggy (*1949) was, because of her androgenic figure, absolutely ideal for presenting unisex fashion. She and her boyfriend and manager Justin de Villeneuve were the most watched couple of 1966.
Mary Quant (*1934 ) - one of the most important fashion designers of the 60's and probably of all times.
