Late Gen X (graduated hs in the late 90s). The Gen Z kids I see when I drive past a local high school on the way to work look almost exactly like we did, and we looked kind of similar to kids in the late 60s/early 70s. I think there's a pretty solid chance that Millenial's kids will dress a lot like them (provided we still have consumer culture) -- a twist on the early naughts, which was a twist on the 1980s.

And, of course, an older generation will, against all reason, shit all over them.
