Thanks Caz! I tried a 16 and a 17. My wrist is pretty close to 6" and the 16 was very snug especially around my wrist bone. The 17 seems much bigger to me. I really wish they had something in between. I don't like my bracelets to move around much but the 16 was so snug I felt like it was too tight. I got the 17 and it does move around more than I'd like but i think it was the right choice.
