This brand has been a wonderful find for those with a smaller ribcage/cup size ratio, but I have yet to find the "perfect" model/size for me.  I think I still need to go up yet another cup size, but the band is just about right.  At first, I liked the way that the straps were buckled with flip-top clamps rather than just the standard ring, but the difference between the strap and bra fabric causes these large, oddly shaped clamps to twist and poke in odd ways.  Also, the free end of the strap slips out of the retaining strip and will occasionally make an unexpected appearance from under my collar/neckline if I'm not careful to make sure it is secure in the morning.  I am also having issues with the hooks in the back causing sensitive, irritated skin, but I cannot tell if it is just this brand, or if it is my own skin having issues.

Don't get me wrong, this is the most comfortable, best fitting bra I have found so far and I suspect I am just a hard fit with a lot of demands.  I strongly suggest anyone who is a hard-to-fit size to give this model a shot.
