For real, I’m a 36 DD and this thing is amazing. I have a great sports bra I love (tata tamer) and I pair them together at bootcamp. It sits just above nipple height (and I wear it over top of my shirt) and no word of a lie, the first week I got it, I couldn’t stop staring at everyone’s boobs (smugly) during jumping jacks or burpees, while mine stayed in place without discomfort. If you look at the video on their site, it’s easy to see how that kind of bouncing would cause micro tearing or issues later on.
