I almost never wear bras, I'm small enough that I don't need to. :D Sometimes my nipple piercings show a little, but fuckit. You know you like it, you dirty pervs. I layer the best I can to keep that from happening.
i don't think women should wear bras around maybe sports bras to exercize in to kep them secure but i disagree with the existance of bras at all i like them big and saggy soft and squishy.
