So I ordered four different Moving Comfort bras. I'm a 36D and wanted something more supportive for those jumping moments in zumba. So far, the Luna bra has been the best. It is comfortable, adjusts like a regular bra - hooks in the back, adjustors on straps in the back - and it minimizes the bounce. It is not completely bounce free, but there is a huge difference between the Luna and the usual cheap sports uniboob bras I used to get. So I'm happy with the upgrade. Another benefit is that it shapes your ladies, so there is no uniboob. It does not give you the VS cleavage effect, but then again, it's supposed to be a sports bra! Also, this bra fits according to the size I have in VS, so I was happy with sizing. Finally, the cups are made of thicker material, so there are no "headlights" problems. The panel between the cups is thinner to allow for breathing. All in all, very comfy, easy to take off, sized well. Just wish it were cheaper!! Oh, and it's also smooth, so you can wear it under a t-shirt. I imagine this would also be a good day to day bra for those of you who need support throughout the day but still want to look feminine.

Re other Moving Comfort bras I purchased:
-The Aurora was super comfy, lovely smooth stretchy material but medium impact, better for activities like yoga or pilates. Buy size up. I got the L, and I need to stretch to fit the last set of hooks. I kept it though, because it's so thin and comfy. Better for summer though, not AC rooms.
-The Juno bra - if you need something for running, this might be a better one for you. It's built like a tank. I returned it because the racerback straps were very thick on the shoulders - supportive for running - but they dug in when I lifted my arms. So less comfy for zumba.
- The Vero bra was very similar to the Luna, but it was not sown as well and gave the uniboob effect. So I returned that one too.
