thats not how it works
why? is it just because their female?
if guys can go shirtless on a beach than a flat chested female should be able as well.
...I am saying this, assuming that there is some sort of condition where their breasts remain completely flat.
And not knowing a single thing based on any rules/laws that might say "cover your tits even if they are flat!11"
bleh. I should have just left it to I like flat chested girls >->
