Beverly Hills, 90210: Spring Dance, circa 1991
We’re kind of cheating here because the seminal dance that everyone remembers wasn’t actually the prom. That was the non-event during season three when a post-Dylan Brenda’s last minute date was star football player Tony Miller (who’s now a grumbly cop on TNT’s Southland). It was season one’s Spring Dance that people are still talking about. First, it was the benchmark moment when Brenda lost her v-card to Dylan McKay (hey, it was a big deal back then, OK?). But the major highlight: The unforgettable “Bitch Stole My Look” sitch when Brenda and frenemy Kelly Taylor both showed up in the same awesomely ‘90s off-the-shoulder black and white mega-bowed mini-dress.
