oh man Thankfully I don't run much anymore so I don't need too much boob support with the elliptical/biking/weights. I miss running though, stupid bum knee. I was somewhat of a late bloomer in the chest department so I had no issues back when I WAS a runner in my first year of college - I didn't even wear sports bras back then. Just regular ones.
I'm allergic to paying more than $20 per article of workout clothing though lol. Usually I wait for stuff to go on massive sale before I buy. "A pair of compression tights for $90? Nah, I'd rather eat $90 worth of burgers."
