Comfortable, and a pretty good fit, although I would recommend getting a large if you are a petite DD. Fully reversible and gorgeous on both sides. Suitable for things like yoga but doesn't provide enough support for active work, if you are larger in the chest (size D upwards at least)

I mainly use the bra for running. It’s feels tight but comfortable, keeping everything in place. I like the versatility of it being reversible and that you can use it as a top to swim in. I’m very happy with my purchase!

I was a little bit wary when I first pulled the bra on and it felt a bit tight, but it relaxed and I was able to wear it comfortably (forgot I was wearing it) all day! I felt supported but still had plenty of mobility for my lats.
