Originally, I ordered this because it looked firm and supportive, and specified that it was intended for D cup size (huzzah!). I also thought that it might hook in the back as well since it had the adjustable straps like a "normal" bra. When it came in, it was basically like every other over-the-head bra I've ever had. I was not at all impressed with the "outer cups"... it was like extra stiching that showed where your breasts should go, but not real functional. Not that it's a bad bra or anything, just not what I had hoped for the price. For reference, if you are buying this bra, I am 5'3" 34D and a M is what I would have gone with.
