I've had people ask me, from time to time, about the type of money belt I use on my travels. It's an ordinary leather belt, but has a zippered compartment on the inside. I trifold $20s or $50s, depending on how much backup cash I'm taking, and slip them in there. You can fit quite a bit of cash in there that way, and it is completely inconspicuous...
