The thing that I like about men's clothes is that sometimes they shrink me, so I look more feminine when I wear them... oddly enough. Also they're comfortable and I like them.
Though you could argue that my t-shirts are androgynous, as they are not marketed to men or women, specifically, being as they are band tees.
My flannels though are totally men's work flannels lol
It really does come down to what works best, aesthetically when placed on one's body. I feel awkward in a lot of super feminine clothing because I am tall and the smaller the clothing the bigger I feel look and I don't like feeling super big, so on goes the looser clothing to shrink me.
The shirt I'm wearing in my profile pic is a leftover from my pre-transition days.
