I was thinking about this again, I think they should do a skin line post Yasuo training Taliyah, so there would be Old Man Yasuo whose clothes are older or perhaps he is wearing a Monks robes with a more decorated sword, white hair and a fuller beard. Taliyah would be more mature and have more vibrant clothes (we haven't seen her actual art yet). Yasuo's wind may be more of a pure white as he has probably been redeemed since the finishing of their training, perhaps training her is his redemption. Just my thoughts!
Traditional Japanese Monk Robes (I am no expert, looked at google) look to be either orange black and white or brown and grayish white (the latter sounds more appealing to me) and they have the straw hats as well. He would look dope in those robes and hat with a cool ass staff or sword.
