36G here. I got a L in the DD+. No complaints size-wise - great fit, no spillage. What I have an issue with is how stretchy the straps are. It's like people with small boobs (or men) got together and were like okay what do people with bigger boobs need - bigger cups, problem solved! BUT they didn...'t modify the straps at all, so this is a return for me. This, and apparently all of their DD+ sports bras, need a limited-stretch strap material. This one was actually better than another style I tried - Transcend Strappy DD. It doesn't help that I'm 5'3 (which is the average height of an American woman, Athleta!). If they changed the material of the straps and/or made them adjustable, this would be a win. If you're tall, or your boobs are significantly farther from your shoulders than mine (which at a G cup is saying a lot) then this might work for you. If not, join me in continuing the everlasting search for a comfortable, moderately supportive but not hideous sports bra that accommodates large cup sizes.
