Just as Nintendo had its Power Line, so too did Sega once have its own band of phone-based game assistance. It was staffed by men and women who were known as Sega Game Counselors, and in addition to their jobs helping kids get past the tough parts of games, they also got these jackets.
This one, from the "Genesis heyday" in the early 1990s, is wonderful. And I mean that in a purely historic sense. I'm pretty sure this was hideous even back then. Now? Your definition of ironically fashionable would have to be pretty messed up to even think of pulling this off.
