Cute sports bra that doesn't give the dreaded uni-boob.  It has removable pads (very thin) so it doesn't show any nipples.

I use it for running and have not had a problem with discomfort.
It's also not overly tight and constricting which is great.
I am .... well endowed ... so I was worried that this wouldn't work well for me, but I'm happy to say that it's great.

I recommend this sports bra (and will probably buy more colors at some point)
