Ahh the sports bra.  Of all of the different kinds of bras they are, these are the most likely to be seen out in public every day.  It might be on the fit cutie running down the street, or if you go to the gym they are pretty much everywhere.  Some may not think they are sexy, but others do (me included).  They don’t show off a lot, but even recent designs are being built with underwire and cleavage enhancements, so even your gym attire will raise your sex appeal.
