It goes without saying that people should be clothed according to their status in society as well as their respective circumstances.
All of the cultivators of the Mount Shu Sword Sect, while dressed differently individually, bore the same type of sword.
The disciples of the Great Void Sect would all be clothed in a robe as white as the clouds in the sky.
The Intense Flaming Sword Sect would all be clad in a brilliant scarlet.
As for the now-defunct Great Thunderclap Temple, they were even more particular in their attires. Their robes came in crimson, bright yellow and graphite. Some of them bore golden threads while other possessed jade buttons. Also, robes differed in the style in which they were worn. Some preferred to wear their robes like a coat while others let it sling across their right shoulders. With the number of monk robes it possessed, the Great Thunderclap Temple could open a clothing retail shop.
The examples mentioned above were hardly mere formalism.
