Who is more sexist? Society or Fashion?

I believe society is more sexist because in my American society a man can still be seen the same if he changes his style, a woman can be seen as: "asking for it",slut, tramp, pure, prude, etc. Society also creates a value in fashion. There is a controversy to this though, society and fashion can both make women feel insecure about themselves. "Only fashion models can pull this look off" is what is often heard and this results into women becoming insecure with their bodies. I have yet to see a high fashion plus-size show.  Fashion usually promotes though like in Marc Jacobs Fall 2014 Show.

If a women was seen wearing this publicly, it would be a statement but she will be seen less than a woman with rights to her own body. 

Men can be half naked and still be seen as a person which is the frustrating part. A woman is valued by how much she wears and a man is valued by his style.
