there is a lot of girl clothes that are very acceptable....
I'm not any different. But I do have some masculine girl clothes too. I LOVE hanes low rise boy brief (available at target). They have a fake fly sown on the front and look very masculine. They actually have GREAT support too.
Boyfriend jeans were mentioned.... I have several pairs of these women's jeans that are supposed to mimic men's.
Shoes, etc...
On other occasions it's fun to be a little more Feminine and daring too when en drag, but only when it's safe.
