The cups on this bra run very, very large - I am a 36DDD and the 36DD has a lot of room left over - and it does not provide as much separation or support as the product image suggests. So far the only brand that fits me routinely is Wacoal, but they don't make a sports bra in a style that works for me, sadly. I would say for the price this is not a bad bra; the construction looks solid; but the strange cup sizing makes it difficult to buy a properly fitting one online. I recommend going three cup sized down - sounds extreme, but you'll regret it if you don't.
