On the off-chance I don't make it to Walmart Labor Day weekend (there are none in New York City, but I'm visiting my parents in Florida and I consider a trip to their SuperWalmart a highlight of my trip. They find that very amusing!!), I remembered my own tip.
Buy a fanny pack that has a shoulder strap. Then, use the shoulder strap as a belt. I didn't even remember this until I found my fanny pack from my last trip.
(If you had a fanny pack, why are you buying another one? Because I couldn't remember what I did with it, and I'm always in the market for a good fanny pack).
