The glitterati gathered at the Gibson Amphitheatre to celebrate the past year in cinema at this year's MTV Movie Awards. But, more importantly, they strutted their stuff down the red carpet in chic (or, in some cases, totally chill) outfits.

The sun might have been beating down on the carpet, but that wasn't the only thing that kept celebrities looking hot, hot, hot — it was also their very unique style. Still, however creative the stars got with their looks (hey, Chris Isaac, way to bring back the dog-as-accessory fad with your adorable white puppy!), there were a few standout trends that caught our attention. And no, one of them is not leopard-print leotards, though we do give major props to Brüno for such a wild choice.

Bringing Back the '80s
Grab your crimping irons and scrunchies, folks, because we're taking a trip back to the totally tubular decade. The '80s were first ushered onto the red carpet with Ashley Greene's neon-yellow clutch and continued with the entrance of Soulja Boy Tell'em, who sported a khaki cardigan with hot-pink piping and a white T-shirt with a neon-colored graphic. Many A-list femmes rocked the trend, including Sienna Miller in a long-sleeved sequined frock with what looked to be shoulder pads (though maybe it was just the cut of the fabric). Lauren Conrad said bye to "The Hills" in a flouncy black-and-red dress that included a tiered, voluminous skirt that so could've made a cameo at the prom in "Pretty in Pink." Also invited to that prom: Conrad's pal, Stephanie Pratt, who showed off layers with her Soltani gown, and Lil Mama, who wore a bold turquoise dress, satin magenta clutch and vibrant yellow stilettos.

Sequins and Beads
There was no doubt that the ladies were going to glow on the carpet, and this year, they sparkled with delicately adorned dresses and accessories. Among the twinkling stars were Sienna Miller in a green mini, Nickelodeon darlings Keke Palmer and Miranda Cosgrove, and Audrina Patridge. Paris Hilton went a bit more subtle with a glittering silver purse and metallic embellishment on her peach dress.

One Shoulder
A few of the women put their best shoulder forward with one-strap dresses. "Hills After Show" and Movie Awards red-carpet host Jessi Cruickshank started off the trend in a mustard-yellow number. "America's Next Top Model" champ CariDee English continued it a hot-pink and orange bias-cut dress. So did Audrina, who seems to be nailing just about every trend on our list so far. Finally, Rumer Willis capped it off with a geometric-print emerald-green mini.

Leather
It's only one day away from June, but the stars still preferred to keep their favorite leather looks going just for the Movie Awards. Ashley Tisdale selected a deep-purple mini leather dress that was cinched with a black leather belt. Cullen daddy Peter Facinelli, Carter Jenkins and "Star Trek" stars Clifton Collins Jr. and Zachary Quinto all rocked leather too.

Gladiator Heels
While some of the girls were rockin' out to the rad '80s, others were stepping into ancient Rome with super-strappy gladiator heels. "Transformers" vixen Megan Fox towered in black stilettos that included six straps. Kristen Bell followed suit with black heels that showed off a few silver grommets. Stephanie Pratt also kicked it into high gear with tiered black sandals, as did Ashley Tisdale in wedges. An honorable mention in the shoe category also goes to booties, which were favored by Leighton Meester, Cameron Diaz, Catherine Hardwicke and, if you want to get really technical, Brüno!
