We're told teens deal with conformity, but every single woman in an eensy mini? This took herd mentality to a whole new level! Luckily, there were bright spots amidst the sea of gams and booties...and, um, Levi.
Black, of course, was popular - if not so basic. Kim Kardashian's version of the LBD is, at least technically, all those things: but better not try to take this one from cocktails to a funeral.
The Vampire Diaries' Katerina Graham couldn't decide between bedazzled and pirate, so didn't.
Why won't the leather kilt-on-red-carpet die? Jenna Dewan, tell us!
Apparently, if we believe Shailene Woodley, The Secret Life of the American Teenager involves some highly dubious shoulder detailing.
Nikki Blonsky, vaguely 40s, bucks the glitz trend with elegant results.
Cobalt was another popular choice, as modeled by Modern Family star Sarah Hyland.
Victoria Justice keeps it simple.
Melissa & Joey's Taylor Spreitler adds cute 70s detailing.
One of the more troubling trends? Booties: something few mere mortals can rock. Emma Roberts, of course, is Hollywood royalty. Not to mention sartorial.
Of course, booties were kind of the least of Lucy Hale's worries.
Jennifer Stone combines all the evening's trends in one getup!
And Ariel Winter takes the trend to its logical conclusion.
The reign of Sparkle Motion continued unabated: Lea Michele was ready for Vegas - in the best possible way.
Mary Lynn Rajskub has never looked more glam.
Keke Palmer goes all-out. Disco-ball-out.
Virginal white's still big, too. Exhibit A: Selena Gomez.
B? Courtney Galiano, bridging white and sparkle.
Kat Deeley, ready for Diddy's White Party.
Ashley Greene went the upholstery route.
Weirdly, the rule-breakers were amongst the most conservative - and successful. Check out Jayma Mays' demure citron.
Also in the top tier, Amber Riley.
I'd say she was really duking it out with Naya Rivera: the Glee ladies represented!
The menfolk were all senior-at-prom. See: Monteith's I'm-still-me shoes.
And Jackson's grudging tie.
Say what one will about Levi, he and his date don't look awful...just kinda prom after-party.
