The inside pocket. Because sometimes you want to go out, but you need to bring some stuff you don't want anyone to see. I have to get a couple of buttons to keep the pocket closed. The bag is large enough to put in a set of keys (if you are the Designated Driver), a bus/subway pass, some ID and that bit of your face you can't bear to be without. If you are one of those people under the control of the nicotine, it will also hold a packet of smokes and your lighter.
I added the small straps along with the bangles so you can dig in your purse without having to take off one of the bangles. Not as aesthetically pleasing as it could be, but handy. In the words of Red Green, "If the women don't find you handsome, you might as well be handy."
