If you saw me running down the street in a sports bra

....Depends on how big your knockers are!!!!

If they're big enough to 'knock', a sportsbra is warranted?

This is America. Why would you care what others think about what bra you're wearing in public?

I think it would depend on the bra. If it provides enough coverage (though everyones definition of that is different) and if it keeps everything in place. If you want to be absolutely safe, wear two sports bras at once. I'm serious. I've heard of people doing that to give extra support during workouts. If you still don't feel comfortable just wearing a sports bra, try wearing a cut off t-shirt over it. That should keep you cool and cover anything you might worry about. I also suggest wearing those cooling wraps around your neck to keep off the summer heat. Don't forget the sunscreen.

Definitely not inappropriate.  I've seen guys/girls wearing far less in the gym.

Where is the problem if you are running wearing sports bras.  They cover and keeps you from jiggling all over the place.

is this more of a question? or just a way to get guys to look at your profile ?
