The thing is, being a teenager kinda sucks. But being a Hollywood teenager is different: you're popular and well-dressed and you get your own awards show! Best of all, you can actually be in your 20s and just play a teen. Hence, Rachel Bilson, Blake Lively, Hayden Panettiere, Miley Cyrus, Scarlett Johannson, Kristen Bell, Leighton Meester and more all congregated at L.A.'s Gibson Amphitheatre, along with a bunch of real teens, to show us the highs and lows of adolescence, sartorially-speaking. And appropriate to the teen theme, they varied wildly, from the sublime to the ridiculous to the really, really ugly - after the jump!

The Good:

I like that Rachel Bilson's entire rep kinda rests on being consistently well-dressed rather than any acting, really.

I must admit, I was pleasantly surprised by Brittany Snow's pretty floral mini!

This could easily have gone awry, but Kristen Bell manages to pull it together beautifully.

Isn't Selena Gomez the one Disney was grooming to be the "new Miley" after the whole VF fiasco?

Leighton Meester aka Blair Waldorf doesn't just play a class act on TV.

Nice to see Natasha Bedingfield looking demure and pretty!

Scarlett works this shape a lot; she can.

Blake Lively always makes being young look so effortless.

Minka Kelly's tan is seriously freaking me out, but I guess her simple white number works with it?
The Bad:

Demi Levato's bondage bellhop from the future is a Don't.

Meaghan Jette Martin's frock is a bit "Eloise at a Bat Mitzvah."

Uh oh. Joy Lauren's vest ensemble: a lesson in bad proportions.

If a jumpsuit, Shailene Woodley's toga party spcial may be irredeemable. If a dress, merely bad.

Lauren Conrad's trendy maxi is a bit Roxy by Quicksilver, no?

I get it, Miley, I do: you basically want to wear the opposite of "being naked in Vanity Fair."

On the one hand, I like seeing Kim Kardashian in something more structured and demure than is her usual wont. On the other, this puts me in mind of the molded-cup dress Daniel designed for the Gristede's Project Runway challenge, and however awesome that was, I'm nor sure it's a good thing on the red carpet.

Who in tarnation is Fergie's stylist, anyway?
The Ugly:

Full-time red carpet exhibitionist Phoebe Price basically has this category on lockdown.
