I find nothing amazing about someone having Selphie's hair cut/do. Something that would be worth a conversation would be someone having Cloud's, or another character with insanely spiked stuff. Honestly, half the haircuts from the Final Fantasy series are perfectly normal and manageable. Would you be astonished if I said my sister has hair like Rinoa, but has never played FFVIII? Or, if my brother had Zell's hairdo a year ago? No, and I don't think Selphie's hairdo is that spectacular either.

(And yes, nik, I believe it was popular way back when.)
