I've only been wearing sports bras for a few years now, and sports bras only at home for about six months now. I'm glad I bought them back when I thought I was an androgyne and still tolerated going in that dept as long as it was a get-in-get-out affair.
Anyways, that really does suck.

Try going to a sporting good store for sports bras, so at least the displays are completely toned down, absolutely no lacy bras, all business. No hot model posters

either but hey, how much can you ask for?
