You decide to go around shopping as a woman. Noting how clothes do not change you should get some stuff to start with, so you start shopping for women's clothing and pretending to get it as a gift for your girlfriend. Once purchased you quickly find a woman pre-set that matches the clothing size and apply it in a change room, then putting on your new clothing without underwear. Now you can either get some women's underwear since you can now enter a women's underwear store without getting weird stares, or just shop with no underwear.
