I have a bunch of fanny packs from back when they were cool. I am hanging on to them for when they become cool again. They're actually quite useful.
I may not have to wait long. The older I get, the less anybody notices me. I am now at the stage where I can wear sandals AND socks (at the same time!), Bermuda shorts, plaids mixed with stripes, pocket protectors, suspenders, and flip-up clip-on sunglasses. It shouldn't be too much of a stretch to add a fanny pack back into that mix.
