The stunning thespian looks like a vintage chintz couch cover. And what's that flap for?

Flipping convention, the most interesting part of Kathryn Hanh's retro '20s flapper frock was the bottom, leaving the beauty a bit "meh" above the waist.

Gaby Hoffmann always demonstrates the courage to do something different, but her delightfully kooky Rachel Comey sequined gown was in a battle against her '80s- inspired asymmetric hair.

For a woman who can make a fitted bed sheet look fantastic, Nicole Kidman's Gucci frock is too busy and trying too hard.

Despite her "Angelina Jo-leg," Sarah Hyland's J. Mendel gown is a bit too simple to really make a statement.

Emily Robinson manages to have her gorgeous features overshadowed by a slightly confusing dress that has all the excitement of a restaurant napkin.

Ellie Kemper's delightful hair, face and flattering top half makes the bottom half of her Peter Pilatto creation look like the fun just sort of stopped.

There's a lot going on here -- see-through elements, textures, a decorated neckline -- and none of it quite jells for Joanne Froggatt.

Amanda Peet's slinky slip feels decadently appealing, but it's greatest strength is also its weakness: She kind of looks like she rolled out of bed.

We love a good risk, but Gwendoline Christie's boxy blue satin steampunk-inspired creation is a no.

Lily Rabe's dreamy Lela Rose is certainly a sight to behold, but we're not sure she shines as brightly with this color choice.

Wearing Dior Haute Couture is no doubt every girl's dream, and that hue is super flattering on Emilia Clarke. But the poofy shape gives us much more "debutante debut" than it does Hollywood glam.

Julia Louis-Dreyfus is just too fantastic for this frock, which feels more "country club lawn party" than her usual red-carpet-ruling choices. Not bad, but not great either.

It truly breaks out heart to put a blemish on the report card of the iconic fashionista Julianne Moore, but this puke-green Givenchy just doesn't look great on her.

There's no other way around it: Michael Shannon's jacket is just ugly. Kudos for trying to be different though!

We're not sure if Lori Petty is on her way to a rave or just parachuted in, but she looks happy, which is really all that matters.

The typically flawless Uzo Aduba made a misstep with this emerald sparkler, which would've been perfect for her turn in The Wiz Live!, but not tonight.

Proving that good intentions don't always yield good results, January Jones' whispery creation somehow feels too busy and a little unfinished.

We love her fresh makeup and the elegant gold embroidery on her gown, but Mayim Bialik gets forgotten because of the gown's lack of shape and distracting sleeves.
