I don't know about you but I have pretty much everything I need to survive for  a good long while, on a deserted island in my purse lol. Everything from makeup, to a library book ! So, I want to know what that one item is that you MUST have in your bag at all times. Just leave your comment below and you've got a chance to win a Kat Couture handbag from our friends at Dillards !
