This bracelet was purchased for my 15 year old son.  He is a skinny, tall lankey young man, and the 8.5 size was not to big for his wrist. With his arm down it hangs just a bit over his hand. It will not be in danger of slipping off.  It is a nice weight, and design. I wanted to give him something a little classy that he could have for many years.  My mother gave me a charm bracelet when I was much younger than him, and now at 50 something I cherish it. This is a great puchase, and I would reccomend it to anyone.
