It also depends in the way your wrist shapes. I went to the store certain the 16 would be too big for me since I have a wrist a little under 14cm. But I found the bracelet is very oval and so is my wrist, so I can push it up, but it still feels comy and not too big worn lower on my wrist. Once I tried it I was really impressed with the design because it fit so well. I was originally afraid I would need a 15, and wasn't prepared to pay the extra cost. Sorry so long, but I would try the next size up to be sure.
