Michelle Monaghan

I actually LOVE THIS. It's seasonally appropriate -- if you can deal with a cold sternum for 15 minutes, which you can -- and it's so lively. For a Thursday night cocktail shindig at the Chateau Marmont in January, this feels totally perfect and fun to me.

Paula Patton

Well, well, well. Look who's back to her old tricks. Paula. I thought we left Too Tight Too Short behind once you ditched Robin Thicke. Let's reconvene about this soon.

Amber Valletta

Amber looks like a gangster's moll who got half her dress caught in the wood chipper, but at least she didn't forget her coat.

Mary Elizabeth Winstead

Full length might be a little much, but, honestly, I think she looks awesome in this. The leather jacket makes it.

Gillian Jacobs

"My kingdom for a leather jacket. No. Seriously. You guys, someone bring me my coat. These chiffon flaps aren't cutting it."

Kristen Wiig

This coat, on the other hand, is hard to see, but once you get a grip on it, it's groovy. It looks like something Delia Deetz would have won in Beetlejuice. In a good way.

Helen Mirren

Well. She is the queen.

Rooney Mara

Note! This was not nearly so sheer inside, or at the other event she attended last night, so I think the paparazzi flashblubs areto blame for this one. Otherwise, of course: Zzz.

Rachel Bloom

She is the titular star and creator of Crazy Ex-Girlfriend, which is great, and I love how much she seems to be LOVING ALL OF THIS.

Paul Dano and Zoe Kazan

They look sharp! I feel like Zoe VERY WISELY decided that pants were the order of the night and sort of just sassed everything up with accessories.

Ashley Benson

Ashley Benson often -- as I know from seeing candid shots -- just goes to the bar at the Chateau. I kind of like the idea that some of the people snapped out here at the valet were actually just inside for other reasons.

Taylor Lautner

Like Taylor Lautner here is TOTALLY just running inside because he left his credit card the night before.

Julie Delpy

She's comforting. Sensible but very elegant coat. Chic glasses. Red lip. Glossy hair. She could honestly just be a high-ranking editor at W, like this.

Gerard Bulter

Gerard Butler WILL NOT REST until he finds his blazer.

Anthony Mackie

Anthony Mackie has wisely gone for the Shirt Sweater Blazer method.

Kate Mulleavy and Kirsten Dunst

Kate, of course, is one of the women behind Rodarte, and I love that cozy jacket. Kiki, of course, looks charming but chilled of leg.

Suki Waterhouse

I am just NEVER going to get on the chain for Suki Waterhouse. Regardless of that, this entire thing looks dug up from the back of beyond.

Jacob Tremblay

Young man! It's past your bedtime!

Chanel Iman

She looks great, if a bit like she's going to another, way fancier party. (Her face also says, "I'm a model. I've been FAR colder than this.")

Jesse Metcalfe

And then Jesse Metcalfe showed up.

Fugs and Fabs: Everyone Else at the W Great Performances Party

There is a SHARP demarcation here between the people who thought, "It's cold. I'm wearing a coat to this thing," or even, "it's cold. I'm going to wear pants," and people who thought, "NO. I DON'T CARE HOW COLD I AM. Look at my outfit!" [Photos: Getty]
