In different countries they are still different, and in different ages. Some years ago high heels and leggins were men only and women were not wearing them and not allowed to wear them. And few centuries earlier (and even nowadays in some countries and communities) dress-like clothing was mostly men-only as well. Even as far as just 30 years ago in my country some traits which are now considered as "feminine" were considered as "masculitne".

Almost always gender roles were pushed on women as form of sexism and because women literally had no rights at all and were forced to look, act or do what they were said. In many countries it is still like that, more than half of women population of the world are still living like that, without rights and with enforced rules of femininity on them (or rules on hiding femininity with burqas and such), while men at same time can be anything (except what is considered feminine by that society) and are changing what "masculine" is whenever they like. In many western countries women get out of this only 30-50 years ago. And just 20 years ago women finally got rights to look whatever - and now gender/queer theory saying again that women must act, look and behave in some ways, otherwise they are not women anymore but non-binaries or transmen. All our hard won autonomy is again under the pressure and questioned.
