How do i get the guts to buy girls clothing n the stores?

I agree with James, who buys me clothes all the time, and I doubt he tells the store people they're for a girl. If you want to dress like a girl, go for it, if people judge you without knowing you, you shouldn't want to know a person like that, and their opinion doesn't matter. Just be your self, and the people you want to be with or care what they think will like you just the way you are.
