Thanks, eugenius. I had never heard (or rather, read) about Vionnet being considered a minimalist, but given your explanation, it seems plausible.
And Crying Diamonds, what you say about mis-appropriation is very interesting. Fits right into my query.
For instance, to many, Jil Sander would be the mother of all contemporary minimalists. But in popular culture, designers such as CK and Miuccia Prada are more closely associated with the movement.
This all ties into my second question. Many envision so-called 'American style' as a combination of minimalism and sportswear. But could this style have really originated outside the confines of America's high design spheres, and rather be really another wholly European contribution to fashion design?
