I have this bra in the 38 F/G.  Normally, I get something that minimizes both the size and the movement of my breasts, since I do a lot of higher-impact activity (and even on the elliptical or stair climber, we larger-chested girls know that a high-impact bra is necessary to avoid a whole lot of jiggling and discomfort).

But since I've been doing quite a lot of yoga lately, i wanted something that would be a bit more unrestricted, since a) yoga isn't just low-impact, it's no-impact, so immobilizing your breasts isn't necessary and b) feeling that restrained when trying to loosen your muscles and flow in a Vinyasa class isn't very helpful.

And this bra is perfect for it, and also really flattering.  I also love the deeper V of the neckline, since yoga shirts tend to be lower cut than what I wear for the average cardio workout, etc.
