I don't think so - my husband sometimes looks decorative - especially when he is wearing Asian outfits. So I think men and women can be decorative, but not sure if a skirt is as functional as trousers at a school, especially if it is short and stops you running, using the elevated playground equipment, sitting comfortably on the floor or getting up off the floor, walking upstairs without revealing your underwear to people behind you or it can get blown up in the wind.
I don't see why some parents don't consider trousers to be feminine as lots of women wear them and feminine would mean something associated with or a characteristic of women.
So am I. Presumably there are trans people and non-trans people who both dress fairly gender-neutral and have gender-neutral names, so not sure what it is trans people are looking for to feel that they are at peace with themselves.
Quite simply they want not to be identified as 'different'! To be accepted as men and women, not as Trans, Tranny, Freak, Poof, Wierdo, Sissy etc ad infinitum.
They want to be able to be what they 'are' and not what the world, particularly some of the religious world, demand that they be.
To put it in a way that you might, just possibly, understand, a forlorn hope I know, they want not to be in a position which is like what Sassy would feel if it were determined that everyone MUST be Haitian VooDoo and if they are not they must be forced to be regardless of how distasteful and traumatic it might be to them!
This is not the best description of the situation but, is, I hope, one that the denizens of this Forum might understand.
