Hm, yeah, but I find that it's much more inconsistent in the other games as in Magvel. In Elibe you get several knights who are close to that age range who have short hair. But I can totally see having long hair and clothes (and generally seemingly not so practical things for an average life) could be a sign of "I'm well off enough that I can wear fancy stuff without being hindered by them". Like pale skin and stuff.
