I would tryYou know what I was considering the cuff but thought that it'll move around too much. I thought that the bracelet would be a more secure fit and move aroubd less... guess I was wrong!
Agree with thisI second that you should try the cuff. It fits quite snugly compared to the bangle. My wrist measures 14.5cms and I have been wearing a size 17 cuff 24/7 since last September. It's very comfortable and doesn't move around much at all. The size 16 cuff may be perfect for you. I'll find a pic to give you an idea on fit!
