The music. Oh yeah, such variety! I loved Duran Duran (of course), Depeche Mode, Journey, Styx, Night Ranger, Scritti Politti, all the hair bands, etc.
The music videos, back before anyone knew what the heck they were doing. There was something so fun about their lack of self-consciousness even though the videos were often unpolished.
The clothes and the makeup! I especially loved the bright colors + black combo, plus the fuchsia lipstick (remember mood lipstick?) and matching nail polish. I could have done without the Madonna wannabe clothes, though.
I hated the big hair because I could never get my hair to stand up that high, even with Aqua Net.
Video game arcades with games that had less than three buttons and one joystick. Anyone remember Tempest? That was my favorite game.
The Preppy Handbook. Still, there were way too many people wearing polo shirts with their collars turned up.
Friendship bracelets.
John Hughes movies. Andrew McCarthy *sigh*.
