I have long hair so this is a must have item for me. If you had hair long enough to pull back then you've worn this on our wrist... a hair tie of course. Recently I came across these hair tie bracelets - Double Wear Elastic Bracelet by Goody.

What a clever idea! It comes in a pack of 3. Black with gold or silver finish, beige with gold finish or silver with silver finish. Granted it costs a little more, but I like that fact that it serves 2 purposes. I love accessories. So instead of a plain black band on your wrist you can dress it up with "bracelets".
What is your must have accessory or item before you step out the door?
