Julia Louis-Dreyfus is self-assurance personified in a classic black gown with lace sleeves and effortless curls.

Laverne Cox rocks the Egyptian goddess look with a champagne gown and braided hair accent.

Brooklyn Nine-Nine star Stephanie Beatriz got serious in this killer emerald sheath and slicked hair. Whoa!

Although we don't expect Emilia Clarke to always look like a Khaleesi, the Game of Thrones actress frumps it up with this blah navy off-the-shoulder gown with ... is that a cape?!

Kelly Osbourne always knows just how much edge to add with this tea-length leopard-print skirt, black top and simple but lavender 'do.

Joanne Froggatt goes modern with this black, form-fitting stunner with cuff and dangly earrings.

Mayim Bialik still depresses us with this funereal gown, but at least the green earrings are a fun touch?

Anna Chlumsky keeps it young and fresh with this bold red, white and silver gown that is reminiscent of a superhero.

Good lord, The Good Wife star Julianna Margulies knows how to own the red carpet. That electric shade of blue and full skirt with gathering up to there makes for a show-stopper.

Game of Thrones star Natalie Dormer brings femininity with style in this one-shoulder, pastel floral dress.

Julianne Moore is a redhead who knows how to offset her skin tone. The simple but beaded emerald gown is a stunner.

Taryn Manning has hit upon the worst color, cut and makeup for a public function. This ghastly ensemble does her no favors ... unless she's auditioning for a springtime Tim Burton flick?

Sorry, but this ill-fitting lavender dress isn't flattering on Amanda Peet, who still can't seem to figure out what her style is.

Keira Knightley has been settling into her maternity red carpet look with this loose, layered yet still festive deep purple eyelet gown.

Viola Davis is confident and classy in this white halter-neck gown.

Ariel Winter is still trying to find that balance between her age -- 17 -- and her mature curves, but sadly, this white dress is not it. We'll give her points on the hair though.

Felicity Jones looks classic and pretty in this simple sheath gown with a criss-cross neckline.

Well, at least Orange Is the New Black star Uzo Aduba knows she looks good in bright yellow because that's the nicest thing about this gown. Unfortunately, the perforated beach-coverup look and odd material looks far too casual for this event.

Hello, stunning? Maybe we should fake-hike the Pacific Crest Trail to look like Wild star Reese Witherspoon. She shows off her fit physique in this skintight, one-shoulder white gown

Sofia Vergara is larger than life in this scarlet gown with peekaboo portions to add extra sex appeal. Also larger than life? That rock on her finger!

Amy Poehler underwhelms in this simple spaghetti-strap navy dress with loose hair.

Wow, Emmy Rossum is stunning in this strapless, full-skirted iridescent golden-gray number.

We're seeing red in a good way thanks to Sophia Bush. The Chicago PD star is taking a break from the chilly Windy City with this strapless, red-hot dress.

Emma Stone knows how to take fashion risks that pay off. On the heels of her pants ensemble at the Golden Globes, she now rocks this man's suit-jacket-inspired coat dress with a tulle underlay skirt. Add a red lip and simple ponytail, and Emma owns her youth in a very easy way.

Although the criss-cross halter neck is flattering, that shade of green and general fit of Claire Danes' dress are off.

Whoa, Jennifer Aniston is really showing off her, um, tan, and all her curves in this form-fitting print dress.

Julia Roberts dons pants again, but can you blame her? This slick black pantsuit shows off so much of her femininity that we don't miss her in a dress at all.

Laura Carmichael looks good in white, but there's something unfocused about this dress that is half-illusion material (with a thumbprint?) and half napkin.

Maggie Gyllenhaal's revealing bodice on this form-fitting white dress should be an advertisement for the power of double-sided tape. The plunging neckline is a great complement to her short hair and dangling earrings. Strappy shoes with gold accents complete the killer look.

Perhaps we're used to Boardwalk Empire actress Gretchen Mol in period clothes because we love this flowing, translucent, sequined gown that's reminiscent of the 1930s on her. The mid-length flutter sleeve and tiny, metallic clutch are sweet, feminine touches.

We really want to like Lorelai Linkletter's dress, since we loved Boyhood so much, but alas, this Wednesday Addams-gone-wrong, bell-sleeved atrocity will never be in fashion no matter what the era.

We like the shirred, blue strapless gown on Laura Gomez enough to forgive the extraneous train of blue ruffles spewing out behind her.

Veep's Sufe Bradshaw shows off a toned arm and leg in this one-shoulder, high-slitted black dress. It's a good thing it's hot in Los Angeles today!

Although Game of Thrones star Gwendoline Christie carries off red well, the skirt on this gown looks like it's on backward. Is that a front bustle?!

Maria Menounos, who are you wearing? The E! red carpet host is, to use her own word, "stunning" in this strapless, champagne-colored jacquard print gown with the best accessory that can be had on any dress -- pockets!

Adorable Boardwalk Empire actress Kelly MacDonald is unfortunately a bit too under-dressed in this cute, but uninspiring LBD. Some judicious accessorizing and a different hairstyle could have transformed the whole ensemble.

Although Sarah Hyland's plunging neckline is a little much for us, we must keep in mind that the Modern Family actress is actually 24 and in that context, looks elegant in the jeweled bodice and tulle-covered skirt. Also, we caught her on the red carpet eating pizza, which truly is a girl's best friend!

Is it just us, or does Chelsea Peretti's black strapless gown seem to suck up the light? That black-on-black diamond print and bunchy gathered waist just make this look messy and unfocused.

Quick, we need a doily! Orange Is the New Black star Dascha Polanco comes to the rescue with this white lace gown that should be adorning our grandma's table in the foyer.

On anyone else, this ensemble would be overkill, but on Joan Collins we'd expect nothing less. From the curled hair and chandelier earrings, sparkly black gown with bow-tied-waist, flutter sleeves, elbow-length black gloves and metallic heels, the grand dame is a diva from head to toe.

We give Emma Myles credit for trying fuchsia on the red carpet, but this strapless gown with a geometric-cut neckline is just too ill-fitting and shows every wrinkle.

There's no Red Wedding here! Maisie Williams rules our Seven Kingdoms in this adorable red spaghetti-strapped flower-cut sundress. Gold heels and a loose updo complete the effortless look.

Melissa Fumero looks elegant in this graphic-topped black and blue gown topped with sleek hair and a smoky eye.

Not to be outdone by her Game of Thrones sibling, Sophie Turner is similarly cute but fashionable in a black asymmetrical, scallop-hemmed dress with cut-out sides and heart-accented strappy sandals. Her long red hair is swept to the side a la Veronica Lake.

Is that you, Gloria? Orange Is the New Black star Selenis Leyva is gorgeous in a rose-inspired gown.
