Maybe something I should add:
It's not that I actually don't pass, it's that I don't know if I pass.
I have long hair, painted nails, wear padded bras and oftentimes crop tops, all of those are considered feminine. And I have pretty feminine facial features (I sometimes get mistaken for a girl).
The problem is that I don't know if this is enough to pass, and I always look too masculine for my own liking, even if others might find me very feminine.
That's the reason I asked for tips on passing. Thank you for all your feedback, hope to receive more tips!
