Jhin's choice of style

So with the new Galio coming out soon, it has come to my attention that Demacia's color isn't particularly blue and yellow as it used to, as a matter of fact it has come to my attention that a lot of demacian champions don't wear blue at all but they wear this sort of ivory with gold lining and black for undergarments. Take a look at both of them basically wear the same fabrics and colors!

Now take a look at Jhin and you'll see the exact same patter here, with different shapes of course but it makes you wonder... is Jhin secretly of Demacian precedence or is he maybe trying to look just by wearing the colors of demacia?? is it mere chance or is there a story behind this??

Or course Jhin isn't just white, gold and black, he also has quite a hint of red wine in places and his gold is less... yellow? but in game he looks a lot like a demacian since you can't really see the details
