keri,
I have seen tons of the ones with the little wristlet, at Claires and stuff at the mall, wonder where they are all at now?
I think those bags on Pumpwear are cute, but expensive. But if your daughter will carry her meter , then it will be worth it to you. Hope you can find something that works.
P.S. depending on what you want to spend, Coach has cute little wrislets, but they are expensive. Check out
