That would probably be going out in only female clothes. I used scarf to cover most of my face, but still.
I like the thrill that comes from the risk of being seen, but I do not want to be seen. The thought of someone finding out and possible consequences scares me. I was naked outdoors many times, but it was more controlled, than going on 80 minute walk vulnerable like that. It's different to strip in a park at night, when noone is around than going out crossdressed through streets and passing other people, that could possibly stop by and start talking to you.
Ultimately I met almost noone and quite quickly went to a place where it was less likely to meet someone, so after time I felt more confident. Still, it's not something I would easily do again. Before this dare I went out crossdressed once, but it was a bit different. Not all clothes were female, I wore a mask from scream instead of scarf and went just for a short walk, though I passed more people back then - this definitely did not make it easier to do that 80 minute walk. After getting a dare and actually doing it, months have passed. To minimize risk I waited for a moment when I was sure I will be alone at home for the day and at night, so I could easily prepare everything, go out and come back without noone at home noticing. Though with the short walk before I went out when I had people asleep at home.
Sometimes I just have days when I am more daring. This task was one of those that actually require some more willpower to commit and do it. I did some other crazy stuff, but this one is probably the answer for this thread. Big city, noone around knowing I do stuff like this, cameras almost everywhere. Usually I do stuff that makes my avoid people whenever possible. Here I just went out for a walk and until I reached safer place and then home when walking back, I risked stumbling upon someone and them realizing there's a man in those female clothes.
I might do crazier things in the future, as I like to push myself further, but for now, this probably takes the cake.
