I am 14.5 with a wrist bone, I fit both 15 and 16 juc but opted for 16. I find the 15 not as comfortable when it hits my bone. mine shifts to the side just like yours (doesn't turn all the way around on it's own unless I force it), I also adjust it from time to time but it doesn't bother me. I prefer the looser look and feel. Like many people here, we're between sizes, but I will always opt for a bracelet I can grow into rather grow out of (not that I'm growing much). I was once told by a former executive, majority of the sa's are trained to sell the more fitted sizes on the bracelets, due to liability reasons. As much as they don't want to admit it, it's a well known issue with bracelet stacking and that causes screws to loosen. So, rather than deal with many customers with complaints, to counter that is to recommend more fitted bracelets to lessen the likelihood of it happening. Choose what you want, not what the sa's push, they aren't wearing it, you have to be comfortable and happy at the end of the day.
