I don't look so closely at women's fashion but from the 20th century on people have had the freedom to express themselves and their individualities and fashion is one of the most fundamental ways in which they do this men and women are equally able to express themselves.
One thing that hasn't changed though is that we still have to hear the new ad 2 or 3 times before it begins to affect us even when we're already familiar with the advertiser in question and have a positive opinion of them.
