Yves St Laurent made it possible for many woman to wear a real “designer garment”. Vogue published a lot of his designs which were made for those who could not afford a couture garment.
His influence in fashion where he made fashion into an art form is immense and will always be remembered as one of the greatest designers.
I found a lot Vogue Paris Original patterns surfing the Internet, most are for sale , some were already sold. Also Butterick and McCall made a pattern inspired by the Mondrian day dress from the sixties.
Yves St Laurent patterns found via
“1949 – Paris Original pattern line began. Paris Originals are very “fashion forward,”
and are very popular. Vogue was the only company licensed to produce the couturier patterns , with the most popular ones being the French designers, especially Yves St Laurent and Givenchy (think Jackie and Audrey!). They specifically contracted with 8 famous French Couturiers including Schiaparelli, Paquin, Balmain, Fath, Molyneux, Lanvin and Heim to provide a couture pattern service. However these were often difficult for the average home sewer – they contain tons of pieces and many women took classes just to learn how to sew these glamorous styles”.
