How much does a summer men's Mongolian robe cost, including boots, hat, belt and pants?

It’s hard to say, it depends on where you do it and what kind of fabric you choose. In Hailar, a single robe made of better fabrics probably costs around 300. Plus the boots are 200. The hat is very cheap, the leather belt is about 300, and the satin one is thirty or forty yuan. You can just match the pants yourself. There is no rule about what kind to wear.
