I quite agree with what is said above. And personnally I'd just say... Uh... Be natural ? That's easy for me because I really don't care about being seen as a man. Actually I find crossdressing in male pretty fun, and really easy when you're a biological man.

I understand that's not everyone's case though.
When I was 17 I was really sensitive to the fact that I wanted to be seen by people as my real self. People not knowing my real self was something very annoying. The solitude of being invisible was burning me. But that's silly. People will never really grasp your true self. Even my mother, who watched and listened to me days and night couldn't. In the end, I stopped worrying about the ability for people to see me as who I was. I don't care anymore. I don't need them for me to exist. If I can get them closer to me, it's fine and fun. If not, that's life. I don't think I'm very different from most cis-people out there, on this topic. And I've dressed as a man for 10 years after that.
Funnily enough, I'm still totally trans. (but I feel a lot better than 10 years ago !) I'm more trans than I ever was. Being a woman is something that lays deep inside of me. I don't even think it's related to gender. I'm quite OK with being a boy. I think it's just something in your guts ; something in your very flesh. That's not related to clothes, in my case, but I might have thought so years ago. That was just a lie preventing me to see the real thing, and peace came with it. Once I achieved peace and happiness, I was able to see what "being a woman" real meant to me. And I started transitionning. Quite a peaceful journey, but still hard and full of pain. I don't think I'd like to have made it 10 years ago, when I was cutting myself and drinking wine early in the morning. It's a lot easier to journey now.

But here again, it's only MY story. Not everyone is the same, and I don't think the "trans" word covers people with the exact same "problem". So that might not be useful for everyone. To me clothes were just a passing neurosis, but for some it can be the core of the problem. I don't want to insult you. In fact I believe there's various very different kind of "trans", and I think all of them are logical and nice. There can be different good reasons to make the same journey. People are truly different.
So if your main concern is the clothes, then maybe it's what you need right now. You most likely know that a lot better than I do. Just be aware than people on the street won't see you as a woman, but as a transperson. That might not be what you want either.
My 2 cents.
Kisses anyway.
