I really like this bag but I don't really want a bag that when I carry it on my shoulder it hangs down way past my waist! Does anyone know how adjustable the strap is? I don't have a Coach store near me to try it on and hopefully it'll be at my Macy's so I can try it on. I don't mind my bag hanging a little low but not too low, KWIM?? PS. Merry Christmas!
