It is so hard to find bras that not only fit, but are supportive! I did a lot of online research before purchasing this bra. I wear a 38/40J (40GG in UK), and I was so worried that there would be something wrong with this bra - I really don't do well when I can't try things on first - but this bra was IMMEDIATELY comfortable, fit snugly, but not too tight - I wore it for a day, and it was like I was barely wearing a bra at all! There are only two criticisms I have, and this may be different for other people with a different body shape, so please just take this as my own personal comments about how this bra fits me.
Racer-back Option: Getting the bra into racer-back mode isn't the easiest, but it's possible. Might depend slightly on your flexibility. The rings are high enough you can do it once you're wearing the bra - I haven't yet tried to do it before I put it on. Not sure that's actually possible, but it's worth a try. Also, I wore the bra in this position for a whole day - to see if it would ease some of the pain in my shoulders - while it did, it also cut into the crook between my neck and shoulders a little by the end of the day. I think for workouts (not all-day wear), this probably wouldn't be a problem. Racer-back is definitely better for my posture, that's for sure!
Coverage/Fit: While the moulded cups and underwire help with the "uniboob" issue, the part that should press against my breast bone doesn't quite make it. On the other hand, I have some bras that press hard enough that they become uncomfortable after several hours, so this wasn't that bad of a fit. I have noticed (and it's not just this bra, but almost all), that the seam along the underside of the band almost always digs into my chest a little. My stomach distends a little (especially when I'm sitting), so after a while, the edge of the band on the front does get a bit uncomfortable.
All of that being said, while the bra maybe doesn't keep my boobs from bouncing at all, I had no issues running around playing Ultimate Frisbee the other day for over an hour, so I would totally buy this again! (In fact, I think I'll go buy another one right now!)
Hopefully, this helps some of you out there looking for a good bra, at a relatively decent price, that will be supportive for active wear, and is comfortable!
