Being trans can make some interactions awkward, but 90% of those interactions involve you not wearing any pants. There's a whole lot of space in between "Cute earrings" and "Let's go somewhere more private" where your trans status isn't relevant at all. And if you can't navigate that space, you won't even get to the point where you have to worry about how she'll react when you disclose.
So don't get too far ahead of yourself. Don't look at a cute stranger and start imagining an awkward conversation about your transness. Talk to her first. Wait until you really hit it off with someone before you start thinking about how she'll react to your body.
That way, you're thinking about a real, concrete, multidimensional human being. And in my experience, those are both a lot more interesting and a lot less scary than imaginary people. (Granted, my experience is with men, but women are people too.)
