First, the GOOD:

Amanda BynesAmanda Bynes
I am in awe of this goddess-inspired gown, and I am thrilled that she finally did something different with her hair. Her makeup is perfect as well. She is tied for my favorite of the evening.

Kate BeckinsaleKate Beckinsale
This is my other favorite of the evening. The color, the tiers, the hair, the makeup. It is all absolutely perfect.

Becki NewtonBecki Newton
I love the silhouette of this dress and the pale shimmer. Her hair is lovely as well.

Ellen PompeoEllen Pompeo
Ellen usually takes big risks on the red carpet, and usually fails. But here, her risk - a bold, shiny gown - paid off, and her hair and makeup are flawless.

Brittany SnowBrittany Snow
She seems to be paying homage to Old Hollywood with this look... the sparkly gown, the big curls. It's fantastic. I could see Scarjo doing this look as well.

Christina ApplegateChristina Applegate
I'm not loving the white eyeliner, but other than that, this look is fabulous.

Sara RamirezSara Ramirez
Not many women could pull off this color, but she looks amazing!

Teri HatcherTeri Hatcher
I can't believe Teri Hatcher made my best-dressed list, but I think she looks very fetching in this floral gown, and her simple accessories and hairdo are perfect.

Tina FeyTina Fey
I think a lot of people may disagree with me but I think this look is fabulous. Sure, it's maybe a teensy bit too casual for the SAG awards, but she looks wonderful.

Cate BlanchettCate Blanchett
This is pretty safe for Cate, but that's okay. She still looks beautiful.

Allison JanneyAllison Janney
I'm not usually a fan of this color but it works on her. And I love her hair!

Ashley TisdaleAshley Tisdale
I barely recognize her in this photo, but she looks very pretty. I like the lines on the dress and the loose, sexy hair.

Marion CotillardMarion Cotillard
This is pure fabulosity. The dress, the glowy makeup, the simple hair... perfection.

Olivia WildeOlivia Wilde
I love this. It makes me happy that grey can be sexy and exciting.

Marcia CrossMarcia Cross
Marcia always wears bold, beautiful colors on the red carpet. As usual, she looks wonderful.

America FerreraAmerica Ferrera
Absolutely flawless. I'm usually not a fan of lace but this totally works.

Kate HudsonKate Hudson
I want to hate this, but I think it's ballsy and bohemian and wonderful.
Okay, now the BAD:

Chandra WilsonChandra Wilson
She looks lovely from the neck up, but this is a horribly tacky dress, and not flattering on her at all.

Angelina JolieAngelina Jolie
Seriously, what is this? I don't have a problem so much with the earth-toned ombre fabric, but this is a TENT. The pregnancy rumors have already started, this is definitely going to fuel the fire. Her hair is blah and she looks old. Yuck.

Nikki BlonskyNikki Blonsky
It's a great color on her, but this dress is totally unflattering. It looks like a sack. And her hair has too much product in it and just looks dirty.

Jane KrakowskiJane Krakowski
I'm usually a big fan of the retro look, but her puffy hair and avocado-colored dress make her look like she's going to the awards circa 1971.

Sandra OhSandra Oh
Nobody, of any size, looks good in a sack. And nobody looks good in a sack topped off by a tacky pink bow.

And the UNDERWHELMING:

Ana OrtizAna Ortiz
Meh. This is okay, I suppose. I'm not a fan of mermaid dresses in general, but I'm trying not to hold that against her. It just doesn't look like it fits her very well.

Andrea BowenAndrea Bowen
There's nothing wrong with this look at all, she looks very nice. But I feel like we've seen this look on the red carpet a million times.

Eva LongoriaEva Longoria
I actually like this gown. Very much. But her awful hairdo kept her off the "good" list.

Debra MessingDebra Messing
I like her hair and makeup, and the dress is actually very cool. But it doesn't flatter her figure at all.

Ellen PageEllen Page
If this was a regular old premiere, I'd give Ellen a thumbs up. She looks very cute and the dress is flattering. She usually looks awkward when she dresses up but she looks very comfortable here for once. Still, it's not appropriate for the SAG awards. I also wish she'd do something with her hair.

Jenna FischerJenna Fischer
I like the color of the dress, and her hair and makeup is nice, but I'm not digging the studs. Not at all.

Michelle PfeifferMichelle Pfeiffer
There's nothing wrong with this, but I think it's pretty boring.

Jamie Lyn SiglerJamie Lyn Sigler
I want to like this, but something about it is off. I can't put my finger on it, though. I do like her short hair.

Rebecca RomijnRebecca Romijn
I think her dress is tacky and the hairdo is unflattering.

Sophia BushSophia Bush
The hair is boring and the dress looks unfinished. I do like the color, though, and she's a very pretty girl.

Kyra SedgwickKyra Sedgwick
I like almost everything about this. The lace whatever on the back ruins it for me.

Vanessa WilliamsVanessa Williams
Vanessa is usually a hot mess on the red carpet, so this is an improvement. But I don't like the bustline of this dress.
