I in general do not think that you can draw a line between art & fashion. fashion is, if you ask me, a understudy of art – it’s all about the allover picture, and here there’s quit clear focused a lot on the more arty side of fashion. Really stylish people is, again if you ask me, like seeing a pice of walking art. But i really do think that fashion/art/music always will follow eachother like day & night.
I agree with you that fashion/art/music will very often go hand in hand but I do also believe there are many connections between fashion and art, however the line would mostly be shown in the way that art inspires fashions and seldom the other way around! Fashion can become a kind of art depending on how it is styled and presented and also due to the level of designing.
