This questions cracks me up. Actually, I go bra-less most of the time because I have a lot of severe back problems, so almost every bra in the world starts to pinch after a couple of hours (and then I'm in pain the rest of the day). But since I'm pretty flat chested, it's a lot easier to not worry about it. But if I didn't have back problems, I'd slap on a bra and not think about it ; )
