The varying shades of blue in Diane Kruger and Joshua Jackson's outfits are complementary without being too matchy. Josh's blue wingtips are a much better "creative" footwear idea than the sneakers-with-formal-dress look he's often sporting.

Note to self: The most important key to Taraji P. Henson's impeccable style is that everything she wears is always perfectly tailored to her figure.

Rita Wilson looks snappy in this black sequined dress and tuxedo jacket.

This light purple is a great color for Laura Linney. She often blends right into the background at red carpet events, so it's nice to see her going for something with a bit more flair. The sleek ponytail also suits her.

Chyler Leigh's unusual and statement-making dress is really knocking us out. Quick initial research failed to turn up info on the designer — if any of you guys figure it out, let us know in the comments.

Gabrielle Union's hair and makeup are really pretty here, and she wears the lace trend well. But we're Not such a fan of the chunky booties for a warm weather look.

Alexis Bledel looks relaxed and summery here. The print has a sweet vintage feel, and the low-heeled silver sandals go well with the dress. We would swap out the leather belt (too heavy with sheer chiffon) and the black clutch.

Yes, it's a little bit '90s Carrie Bradshaw, but somehow this sheer Gucci gown still works on Rosie Huntington-Whiteley. Maybe it's the whole former model thing.

Fergie reverts back to her usual red carpet look — streetwalker style and event-related inappropriateness. (See the next photo for an example of what other people were wearing to the amfAR Inspiration Gala in Paris.)

Diane Kruger exudes glamour in this grecian-style red gown.

This dress just swamps Kristin Chenoweth's tiny figure. The oversize clutch just adds to that impression.

We love Rutina Wesley's light beige swing dress and those silver medallion earrings. But her shoes are just too busy and distracting. A thin-strapped black or silver sandal would work better.

Evan Rachel Wood's new short haircut is fun, but it all goes downhill from there. The shirtless vest and dangling suspenders are especially painful.

There is something way too middle-school-dance about Anna Paquin's dress. The sheer inset with the purple tinsel embellishment just looks cheap.

This strapless ivory dress looks great on Brittany Snow — it really accentuates her blonde hair and glowing complexion. But what gives with the stripper shoes? Silver-glitter stilettos belong to a different outfit entirely.

Black slip dress, black peep-toe shoes? Check. Pauley Perrette does tend to wear the same few looks over and over, but she just looks so darn cute that we have to give her a pass.

Though we might normally find red pumps to be a bit much with a red dress, Garcelle Beauvais proves to be the exception to the rule in this lovely chiffon number. Love her hair down, too.

Poppy Montgomery sidesteps the nude dress trap by choosing a variation that accentuates her skin tone rather than matching it too closely. It also plays well with her new red hair.

For someone with her means and fashionista access, Katie Holmes just never seems to look as good as she should. This whole look, from the pose to the clothes, is just... awkward.

We know we seem to be spending a lot of time on Elle Fanning lately, but this outfit was awfully hard to resist. The fairy-like Marc Jacobs dress and dark pink leather slingbacks make a perfect dressy summer look for a young teen.

In a nod to his Texas roots, Matthew McConaughey wears jeans with a cowboy hat and boots, while girlfriend Camila Alves opts for a more typical Hollywood style in this pink, body-hugging dress. We still think they look hot together.

Krysten Ritter looks soft and pretty in this Alice + Olivia silk and chiffon dress. The crystal-embellished bodice keeps the pink nude color from being too overwhelming on her fair skin.

The pretty red pattern and bold sash on Famke Janssen's dress offer a less traditional red carpet style, which is nice to see. We just wish she'd gone with something a little jazzier than plain brown sandals. And she could use some jewelry.

Even a supermodel like Gisele Bundchen can have an off day. The pink "belt" looks like one of those bowties that come in a package with a cheap tuxedo shirt. Plus: The top is droopy, and her hair and makeup look more appropriate for the gym than a red carpet event.

Elizabeth Hurley's Roberto Cavalli gown fits like a glove, and the dove gray is an unusual and striking color choice. Her eye makeup is a bit zombified, but we're feeling generous.

Castle star Stana Katic is unrecognizable in this Regency period hairdo and droopy dress that looks like it's been stolen from the Olsen twins' closet.

An all-over shiny gold pattern is a tough sell, but Laura Bell Bundy makes it work by keeping everything else low-key. (See the simple strapless design and minimal jewelry and makeup.) The light gold satin peep toes are a refreshing change from the nude pump.

Fashion forward? We guess, but that doesn't mean we have to like it. None of Nicole Kidman's choices seem to go together — the velvet top half with the sheer bottom, the lavender shoes, the messy bangs...

Jennifer Nettles manages to wrangle a potentially problematic look (a big one-shoulder ruffle mounted on a lacy top?). She balances it out with soft hair and makeup, a plain leather skirt and sleek shoes.

Sheryl Crow's dress is perfectly acceptable — until you look closely at her left hip. There you will find a design "accent" that resembles nothing more than a multi-colored creeping fungus.

Emerald green is a great color for Paz Vega, but the whole look leaves us a bit flat. A different shoe and bag would have served this outfit well.

Elle Fanning sports a sparkly '70s version of the trendy maxi dress. She looks charming and age-appropriate.

Christina Hendricks takes a more casual turn on the red carpet, but this look really suits her. The cropped tuxedo jacket flatters her form, while the blue satin pumps and green clutch offer unexpected touches of color.

Turquoise is a pretty color on Kristen Wiig — but this gown is bordering on bridesmaid. (Admittedly, this could be a subliminal influence.)

Olivia Wilde normally achieves great heights on the red carpet, but this tank top and skirt just look shapeless and uninspired.

So many fashion don'ts here! Claire Forlani's dress is wrinkled, and it's one size too big. The color is also too close to her skin tone to be flattering. And that's just the dress.

Jena Malone attempts to cheer up her sad dress with red shoes. It's not working.

Leelee Sobieski is the latest star to jump on the yellow trend. The color looks OK on her, but the style of the dress feels just a bit tween, and we're not loving the black platform sandals.

Gina Gershon channels style icon Audrey Hepburn with her classic updo, '50s-influenced dress, and simple black pumps.

Bold colors look terrific on Iman, but those clunky black sandals seem to belong to a different outfit. And the neckline of the top just seems a bit off.

We would normally advise against head-to-toe gold. Heather Graham is the exception to the rule in this Donna Karan dress with matching platform sandals.

Allison Janney went shorter with her hair last year, and this is the cutest cut yet. The tie-neck blouse is a nice detail, and though ballet flats are rarely seen on the red carpet, they work well here.

Olivia Munn's dress just looks like a nightgown, and not a very flattering one at that. Those mud-colored pumps don't belong anywhere near this dress — or any other outfit, for that matter.
