^ i too agree. i think you can do it at any age, just be smart about the charm choices.
besides its meant to be playful and fun. if you are wearing a casual outfit or going to the beach or whatever the Juicy charm bracelet is definitely a cute accessory. (they're totally affordable too)
im not one who wants to dish out hundreds (or thousands) on costume jewelry. you can wear it, change it out, or give it to your daughet, or neice or whatever ya know..
