Another exhibition in the Stedelijk Museum was about Fashion and Jewelry designs by "Gijs Bakker (1942)" and "Emmy van Leersum (1930-1984)". In the late sixties they, both trained jewelry designers, created a furor with their avant-garde jewelry and clothing that fused fashion, design and art.
The most famous item was this Stovepipe Neclace with matching bracelet, now an icon of Dutch design.
Here a range of their bracelets. I loved those very much at that time and I still do. I wore simular jewelry at that time by another designer.
Here some examples of their legendary fashion show of 1967 in which they mixed their designs with fashion.
Here a Link to the Museum website.
