Question about diexie dai (belt)

I received the following question from @aarghc about diexie dai. As I'm not familiar with belt construction, perhaps some other readers might be able to provide insights?:

I'm trying to understand the structure of 蹀躞带 dié xiè dai belts. There are many pictures where the hanging straps are clearly one layer, but here (https://fuckyeahchinesefashion.tumblr.com/post/664758617722994688/%E8%B9%80%E8%BA%9E%E5%B8%A6-di%C3%A9-xi%C3%A8-dai-by-cromartie) and other places where you see them hanging pouches from the belt, the hanging straps are 2 layered. From a modern construction perspective it would make sense for there to be snaps on the hanging straps to attach to the pouches but if not, then it looks like it's just friction holding the pouches to the belts? That's now how I'd like to secure my wallet. 8-) Might you or your readers have any insights on Chinese utility belt construction? 8-)
