Okay, I think this is going to be one of those step-by-step sections where you actually need the words to explain what is going on. I hope it's clear!
The pictures aren't the best either because of the way the metal reflects the light. Oh well.
So here's what I used: lead foil and 30 gauge stainless steel fishing wire. The good thing about fishing wire is it's not really maleable, so it will stay in whatever shape I bend it despite constant handling.
1) I used needle-nose pliers to bend the wire into a buckle. Looks easy, but it wasn't. VERY hard to get each buckle (I need 6 of them) exactly the same shape. I made a jig with the intention of pulling a thinner, softer wire (like copper) across, but I didn't have great success.
2) A piece of straight wire to make the "tongue buckle" (that's the little spoke that holds your belt at a certain notch). I bent it slightly at the end to keep it falling from falling through the notch later on.
3) A small piece of lead foil with a tiny hole punched into it.
I pushed the "tongue buckle" through the hole and secured it with a drop of superglue. Then I placed the buckle itself next to that, and finally placed the edge of the foil over the whole thing and glued that down:

The other end of the belt - I cut the end into a point and pushed some evenly spaced holes into it:
Because of the previously mentioned curved part of the "tongue buckle" I can actually move it a bit (it's delicate so not *too* much) to push the other half of the belt through and insert it through the buckle. Basically it functions like a real belt would:
I added a little fastener of lead foil to hold the tapered end down.
NOTE: I screwed up a bit here - I meant to make it extend a little further than it currently does. It'll look more realistic and 3D if it's not fastened so flush to the strap below it. I'll correct it on the next one I do... I look at this one as practice anyway:
And here it is against the figure's leg. I would now just need to cut it to size before I glued it down:
