Lez: I want to butch myself out a little, but I'm not sure...?

Just dress how you want. You can cut your hair in a short pixie style that's really popular these days. You can dress however you want. It'd be fine to dress in jeans one day and a dress the next. Or just dress up for special occasions. Do what you want and be happy. Also, it seems that the more fem girls are more popular. That's just to me though, but I don't know. I'm what most would describe as 'butch' and I'm attracted to 'butch' girls as well. So, it varies from person.
