Speaking just for myself, I quite like her concepts, though reports say she wasn't particularly friendly, not suffering fools gladly and of course she nurtured exclusivity - quite a money spinner in any age.
I'd like to have seen her skiwear.- my own took some finding and was always black with green trim, minus decals and anything else breaking up the trim. Gore-tex in those days was not yet universal. Boots black, skis plain.
Those who saw the rare fashion post at the start of my blogging:
... will know I like plain with the variation in the accessories, same for boats. However, let's get off that topic and just look at the lady who passed away in 2013. If you look about for material on her, as distinct from Mary Quant, you'll not find a lot.
Why not? She was quite the thing - then to die in obscurity.
