Your post resonated with me in some ways, and I hope sharing my thoughts will help you figure yourself out.
Much like you, I've always been rather feminine in the way I prefer to present myself and interact with people. However, I've always been attracted to women, and I always thought it would be easier to be a straight man, rather than to be both transgender, and lesbian. I suppressed much of my personality so that I wouldn't be thought of as gay. Not because I'm homophobic, but because being thought of a gay man was the complete opposite of who I am.
I began to accept myself as transgender when I realized that even very effeminate gay men did not like being thought of as female, or having female pronouns used on them. In contrast, I secretly leapt for joy every time someone took me for a woman, or commented that my manner of interaction, thought process, or physical appearance was female.
When I started transitioning, I pushed the issue of sexual orientation to the background, so I wouldn't conflate the two. I decided to figure out who I was, before thinking about who I wanted to be with.
You mentioned you liked wearing tight-fitting, feminine items of clothing, and I do too.
Here's a thought exercise I found useful: Imagine an outfit you would like to put on for a social gathering, maybe a dress, stockings, heels, skinny jeans, V-neck top, etc. There're two identical sets lying on your bed, the only difference is that one is labelled for men, while the other is labelled for woman. Which would you choose?I chose the clothing with female labelling.

p.s. I'm a big fan of Elysian Fields too! Lately I've been listening to Emily Jane White. Her album "Dark Undercoat" is my favourite so far.
