He did, he looked a lot less boyish (maybe that’s why people were not happy with it? Idk), more sleek to me. Those costumes I don’t think would go with his hair super curly (like say Cup of Russia hair) but they go well with either the short cut or the slightly longer hair with slight curls ( like in Worlds which I think was his best look so far. His hair was perfect cut, length, right amount of curls. The perfect ratio

)
Also as a general observation, Nathan looks different to me since olympics in the sense that he had more of a baby face before and I feel like that experience alone aged him 10 years (in a good way, like more mature even with his extra curls).
