i wonder if there's something you can put on it to size it down a bit...kinda like how you can get something to put on the inside of your ring to temporarily size it down? you know what i'm talking about?
What I do is wear the pony tail rubber band things. They aren't the really thin ones, but the thicker ones. It will add a bit more to your wrist and maybe if you wear a few the bracelet wont slip.
