Fits perfectly, not too tight. Great support. Great movement. And I love that it's not too low at the front!

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!
