Basically, a tool for determing what kind of sports bra one should wear according to chest size and the intensity of the activity. I offer this only as a public service. Thanks to C.D. for the link.
And what an important public service this is, too. I sen it to all my concerned god children in Iraq. I’m sure they’ll thank you
