I regarded myself as a crossdresser for some years before I realised I'm actually non-binary - a whole load of tother complications, but not relevant here - except to say that now I wear a mix of male and female clothes and go out most of the time in make-up and with a bag. I don't wear some of each gender's clothes just to prove I'm non-binary - I choose what I like and that's how it comes out. As Katie says, it;'s not jus theclothes that make you feminine - I can be quite girly in a man's shirt and pretty masculine even with all women's clothes on. But I do have boobs and wear a bra all the time, so that's a gender boundary crossed every morning when I get dressed.
I've been out fully dressed, with skirt, heels, stockings, wig and make-up but it just doesn't feel right to me ( quite defferent feeling to being nervous at being 'outed', which I still get occasionally. I've done it for parties and quite enjoyed it; for everyday situations the blend is the weay to go for me.
If you're crossdressing for sex, that's probably not the same, but I'd say that in general, just keep pushing it a little further unitl you can get the look you like without feeling uncomfortable wearing it in public. Doing that has made me much calmer, happier and pleasant, and I do finally feel that I am being myself. There's no shame in being a crossdresser, any more than being gay or a trainspotter, so go ahead and do it, I say.
