it is related...yes...
depending on HOW you wear them..
remember...
it's about the context...
women wearing trousers is not a big deal in this moment...
but in the 20's/30's it was unheard of...almost scandalous...
VERY avant garde..
so, yes...
classic items can take on an avant garde vibe if they are worn in a new or unexpected way...
i think that a lot of people who wear avant garde designer clothing items tend to combine them with very classic pieces actually...
otherwise it can be 'too much'...
and it is no longer tasteful or elegant...
it just becomes a silly costume...
which you might be able to get away with if you are bjork or some other stage performer...
but for real life...
one does have to consider practical matters...
ie- a margiela top with no armholes, while interesting as a concept, is a bit difficult to cook dinner in...
