I've been thinking about improving my Mal cosplay by making my own suede Browncoat that'll be much more accurate than the canvas duster I had been using, but I absolutely cannot figure out what the buckles are. I've done tons of searching for metal buckles on Amazon and eBay, and I can't find anything close that's the right size. The closest I've found are watch buckles, but they still don't look that similar and they're rather tiny. Here's what I'm talking about
And a closeup on a buckle:
I can see how it works, but I've never seen anything like that before, so I don't know if it's something that's actually used in real life or if they designed it for the show. Does anyone know where I might be able to find something like that, or at least what that sort of buckle would be called?
