Are there any hanboks that are easy to move around in?

Short brown, this is what the farmers wore, linen or cotton fabric, wearable, workable, but definitely not pretty.

Additionally, I don't believe there are any left, after all, they're extremely cheap and no one would keep them.

And it's not pretty, so I'm guessing no one will copy it, so, Dada, you might as well just die.

Instead of looking for a ready-made one, it would be faster to find a designer for a set of plain clothes with a hanbok style yourself.
