This bra fits me perfectly and is the most comfortable bra I own. It's a bit intimidating to get into, but once I put it on, I actually don't notice it anymore. The straps are comfortable and fit just right; the back support feels good (though not sure how much it's helping with my posture). Nothing digs or makes bulges. I thought at first that I didn't have too much cup support because of the soft cotton cups, but even that support was really much better than I thought. I love the bra and will probably get another. If basing it strictly on my size, shape and needs, it's 6 stars!
The reason I didn't rate it as highly as some others that I've purchased is that I can see how it might not work for a lot of people (as I read in some reviews). There is no way to adjust it. No strap adjustments and as with all front closure, no adjustments there either. It is possible that, because of the way it's made, it stretches to fit, but I feel more like I lucked out, and am delighted.
I bought it through Amazon, and it had the return at no cost option, so it's definitely worth trying! Make sure you measure properly because this is the first ever that fits as is!
