Olivia Colman in Stella McCartney

Well, I'm glad Olivia changed in a sartorial way, though in an existential sense I hope she never does. However, I can't say I'm glad she changed into THIS? Those little trailing pieces look every bit as annoying as her other train -- possibly more, honestly, because they're lighter and thus floatier and far more likely for her to forget about and find herself in a terrible flambe accident. Also, it's just sort of crinkly and a bit stale, like a nightie. Her smile, though, is glorious.

Regina King in Monique Lhuillier

After a really active Globes -- surprisingly so -- Lhuillier had a chill Oscars. This is so far the only one we've seen, right? It's... fine. I wish it were sleeveless, I think. Those sleeves OR that neck ruff, but not both, and I'm frankly not wild about either.

Chadwick Boseman

He and Olivia BOTH changed into something that will be more likely to show whatever you might spill on it. STRESS.

Allison Janney in Lela Rose

I would have guessed Brandon Maxwell for this. Nice work, Lela. This kind of thing could get her more calls from either Duchess -- it seems more Meghan's wheelhouse but I'd love to see this sleekness on Kate, too. Anyway, the point here though is Allison, where it is currently, and where it looks smashing.

Brie Larson

This seems to fit better than her silver Celine, but man, do her toes hate shoes. 

Linda Cardellini

This makes sense to me -- she ditched the feathers that would have gotten absolutely savaged at this party, but kept things festive.

Laura Harrier in Louis Vuitton

I think it's inarguable that this concept is an improvement by removing the shirt with the giant sleeves that joined it on the runway, but it also seems way too casual for this party. She genuinely looks like she stuffed herself into a bag that once held oranges.

Emilia Clarke in Rosie Assoulin

This dress, to me, makes the "You lose" trombone noise from the Price Is Right.

Kacey Musgraves in Versace

Ehh. It's fine? It's better than her pink frock, which apparently did have hidden sheer components. I just... listen, I respect a person's desire to do whatever they want with their face, but Kacey is merely 30 and I feel like she has gone too hard too fast on some injectibles. I have long thought this, but this photo really seals it.

Letitia Wright in Erdem

About my earlier comment with Lucy Boynton's Rodarte, where I said it felt like they figured out she liked Erdem and just designed in that spirit. Well, this IS Erdem, and the little armpit bows kind of affirm my Boynton theory. I find this to be very, very twee.

Amy, Tina, and Maya

Tina's dress is fine. Maya's dress is very big. If I were either of them, I would not have changed out of what I already wore, ESPECIALLY Tina. She got basically the only good thing Vera Wang has done in eons. RUN WITH IT.

Amy Adams in Alexandre Vauthier

Very sexy. Only mildly more conducive to eating snacks.

Jennifer Lopez in Zuhair Murad

"HOLA LOVERS. Listen. I did an Elvis tribute. I sang a Motown tribute. At the VMAs, I did a me tribute. Why did I not also do the Queen tribute? Do people not understand that I am one of the most tribeautiful people in the world? So, I changed into this just to remind people of the leg they could have seen if they had not been so stupid."

Ruth Carter

I am actually not sure this base dress is any different than the one she wore at the telecast, but she DID take off the large cape and then add a new accoutrement, so I am giving credit for resourcefulness.

Serena Williams

She really should have stuck with her first outift. I... really do not care for this. Also, those are not her normal lips. What did she DO to them between the telecast and this party? Do lip plumping glosses really work that well, or did she run afoul of a bee?

Tessa Thompson in Chanel

Her other Chanel seemed perfectly reasonable to wear all night. WHY did she change into this heinous tulle bag? Switching from one annoyance to another is one thing, but from one seemingly easily wrangled outfit to a terrible fussy one is just bizarre.

Jennifer Hudson in Christopher Kane

This, however, is a superb upgrade. Rare it is that I like a Christopher Kane, but here we are, feeling new feelings.

Glenn Close in Armani

SPEAKING OF FEELINGS. This is custom. This is another Cape of Triumph. Oh, GLENN. I hope you are okay today. I'm SURE you are, but how could you not be a little bummed?

"Aw, shucks, well, what's a girl to do?" Star in a Sunset Boulevard movie remake to go with your Broadway version, maybe. Or, pick another queen. Eleanor of Aquitaine. Mary of Teck. We can find one.

Angela Bassett in Vitor Zerbinato

Thr cut of the sparkly parts is making you look right at her crotch. This whole night was a rare styling misfire for Team Bassett.

Laura Dern

Cool idea; don't understand why it needed to be SUCH a distinct bra.

Meagan Good

That's quite good on her. Dylan will prefer it to her red-carpet appearance.

Michael B. Jordan

It makes sense to wear a suit that looks rained-on WHEN IT IS ALREADY RAINING, but this? Oh dear.

Adam Lambert

Pass.

Constance Wu in Versace

Oh, I love this. I wish she'd worn that to the ceremony.

Michelle Yeoh in Elie Saab

Elie Saab got a LOT of placements this year. A very similar set of gowns is coming on Heidi Klum -- but, you know, Klumified. Anyway, this feels exactly right for La Yeoh.

Lucy Boynton

That is deeply awful.

KiKi Layne in Versace

For some reason, as of this writing, NONE of our photo sources had the front view. I will update if it comes in. But it's really neat. She had a great night.

Gemma Chan in Tom Ford

That dress is the stuff of a very glittery sasquatch.

Molly Sims

This made me laugh. Is Molly Sims fun?

Ashley Graham

And a big WAH-WAAAAH for La Graham, who looked a career-best on the red carpet, and looks like the mother of the bride at a pirate's courthouse wedding who got frisky with one of the mateys in a closet.

Danai Gurira in Gabriela Hearst

The proportions of the coat and pants are a little overwhelming, but her head looks perfect.

Leslie Bibb

Pass. She didn't have a great sartorial night either, frankly.

Melissa McCarthy and Ben Falcone

"Bye, suckers! See you inside, where I can breathe and easily use the restroom!"

Melissa McCarthy, Bless Her, Changed Into A Full Tracksuit For The Post-Parties

Herein: All (we hope) of the celebs who changed.
