Clothing traditions tend to adhere to gender norms, which, as you say Galaxy, is not related to sex. I understand that there are complexities at play, but in many cases I think that removing gender-based expectations would make lives easier for a lot of people- particularly young people who identify as gender-neutral.
It is, as trisher says, easier for a woman to wear clothes that have previously been considered ‘male’ than the other way round, but it doesn’t have to be that way.
Similarly, removing behavioural expectations based on gender and letting people choose to cross traditional gender boundaries whilst keeping to their own sex would be a lot less binary than clinging to old gender norms and expecting people to change sex to conform to them.
Regardless, I don’t see the need to expect women to make way for the relatively small number of men who want to change sex. We can still be women, and they can be honorary ones. The cynic in me can’t help feeling that if they want to be ‘real’ women they should learn to stop pushing for their needs to come first all the time - that seems a very patriarchal way to behave
