Fong-Leng opened her studio in the P.C. Hooftstraat in Amsterdam in 1971. It was there that for ten years she designed extravagant and spectacular haute couture creations that caused a considerable stir, especially as she also showed them in unusual locations like football stadiums, museums and swimming pools. Fong-Leng’s creations embody the spirit of the seventies. She was the first within the Netherlands to introduce fashion with an international allure and in retrospect she appears to have inspired a later generation of designers, such as Viktor & Rolf who even dedicated one of their shows to her. Fong-Leng’s theatrical dresscoats and skirts with appliqués bear such colourful names as Bird of Paradise, Radiant Coat and Chinese Lovers. Her most conspicuous client was Mathilde Willink, the wife of the painter Carel Willink. Mathilde purchased her entire wardrobe for five years from Fong-Leng. In 1975 Carel Willink painted a portrait of his wife wearing Fong-Leng’s Leopard Coat, a stunning creation made of gold-coloured suede and leather with appliqués and floral motifs. Fong-Leng closed her studio in 1982 in order to devote herself to interior design and art. She continues to enjoy enormous fame, a sign of the great impact of her clothing in the seventies and eighties.
