First the positive. It's cute on, and looks good under a running shirt with the little modesty panel. However, I had both straps at their tightest and it still had a lot of bounce. Also, it does not have an underwire, which I must have missed in the description, because it appeared to me that it did. There's no separation, just a huge gap in the middle pushing outward, unlike the pictures. One of my pet peeves with sports bras is when I have to reach in and separate the girls. Just a pain.
