Lol, as a girl I just wet down my hair (it was shorter though - not butch, but yeah), brushed my teeth, put on deodorant, threw on a tee and pants and headed out. I'm sure that there were some people who judged me silently but for the most part, no one gave me a bad time. Honestly, I can't recall ever being harassed for the way I dressed or for not wearing makeup. I was only harassed for my appearance when I had BAD acne, like pizza face acne...with mild acne I was left alone. There were times where I'd have like 3 or 4 pimples and never wear make up and no one cared as far as I could tell. I spent years like that.
I think, in part, it's all about perspective. As a teenager, I was insecure, and I felt ugly because of my braces and my broad yet skinny figure. But no one ever called me ugly, or bothered me, and people treated me with respect in stores and stuff. In my early 20s, I did not give a single solitary f* if anyone thought I didn't dress right or look right. Part of that was because I was a "lesbian", so if a guy didn't think I was hot, that was great! haha. But beyond that, I realized that even if I was the sexiest thing to grace this earth, people would hate me for something or other. There's always going to be people who judge, and no one can ever truly escape that. I valued my own comfort over fighting that impossible battle. And I had plenty of people who loved me, respected me, and yes, even found me sexy.
