I think Angela and Sandi have the right idea Jen: if you can keep a lid on the fear, you don't really have to be all that convincing. The first time I left the house was only in 2019, without even a wig. But I noticed that the better I felt about how I looked, in terms of clothing, makeup and wig, the easier it got. But at six feet without heels and a bit tarty, I have little chance of blending, let alone passing. But like everybody here says, you can move around in public dressed as a woman without much difficulty if you choose your locations. Personally, I find it quite easy to get a really early (and hence empty) Srassehbahn (tram) into the centre of town, where the boulevards are wider, most of the people are tourists rather than locals and it's easy to vary ones route to suit the conditions. When if it starts to get too busy for comfort, you can go home.
