Uhm, see, I'm MTF, and men wearing women's stuff generally causes a ton more problems than the contrary, right? Well for two whole years before coming out this autumn, I've been looking mostly female at school most of the time, with my only male pieces of clothes being t-shirts (because seriously, a feminine top on a guy just does not do) and coats (androgynous ones, and because I didn't have the money to get new ones).
It made me feel a lot better. In my previous two years at college, in a different program, I'd left on depression three times because I couldn't cope with the dysphoria of being seen as a guy. When I chose a new program (because redoing the same math, history and science gets old), since I was "on the road" to transition (I was waiting to see the psychiatrist who'd see me for eventual endocrinology reference), I decided not to let myself be put back anymore, and I decided to be more myself.
I wore female-but-not-girly jeans, shoes, sweaters, socks, mittens, hats, scarves. To most strangers I'd pass as female. (Even if they knew my 100 % male name, which made me happy, but ahem, irrelevant). Strangers saw me as an ugly girl or person of doubtful gender or very feminine guy. And frankly that was 100 times better than being seen as male, to my surprise. Rarely I'd even get an accidental she. Sometimes, rarely, people would whisper or debate about my gender. I did the airhead and ignored it, and laughed as if "ahaha, you're funny, what are you asking" at the very rare questions, which dismissed them. Surprisingly, no one asked about my feminine voice, which should be the oddest thing for a 22-year-old.
I was loathing the in-between stage, and I thought it was 100 % female or nothing. I just wanted to be normal. Of course, I always did want to be normal. But experience taught me that being in between is still a lot better than being unilaterally on the wrong side.
My classmates, who knew I was supposed to be a guy, simply didn't see me as not a real guy. No one had a problem with it. Like always and ever, I didn't have friends, but I was on friendly terms and talked to over 3/4 of the people nicely, and things went well.
Even, this paved the way for my coming-out. When I did, two weeks ago, the reactions were almost disappointing. There was almost nothing. Because it felt normal to people, it explained things, and who knows, maybe they even knew about transsexualism and suspected it. If anything, things have just gotten a little better. I guess a feminine guy is weird than a trans girl. It may just be that I'm the one who's more comfortable, but I have a feeling that people are talking to me more comfortably.
Now, you're not a girl, you're a guy. And you may not be a tomboy or butch lesbian, but you should be thankful to them, because they've literally made wearing male-ish or even literally male clothes, short of classic suits, acceptable and even borderline normal for women. So even if you need to be seen as a girl, you can dress as you like. Hell, I think you can wear your binder and chances are that people won't notice or ask.
If you don't have classes with many people who know you relatively well, I think you could even transition without saying a word, and people might even say "oh, but it was a guy all along - much more obvious with his relooking", depending on your passing and how much of a female act you might have put up before.
Really, whatever you choose, I think you can do literally anything to make yourself feel better. Look at what I did, and got away with, with a smile. And I think your possibilities are probably greater.
