The red carpet wasn’t the only place that was serving fashion’s finest looks last night. Actresses like Ruth Negga, Isabelle Huppert, Emma Roberts, and Brie Larson were dressed as well for the Oscars as they were for the after-parties. Plus, there were several dresses to dream about on actresses and celebrities that didn’t attend the actual awards. Below are some of the best looks from Vanity Fair‘s annual Oscar party.

Ruth Negga in Oscar de la Renta
Fierce. The paint splatter effect of this sequined tea-length gown was a nice contrast to the romanticism of Negga’s Valentino dress from earlier in the evening. Two knockouts and yet another win for designers Laura Kim and Fernando Garcia.

Isabelle Huppert in custom Armani Privé
Only a trim and terribly chic French woman could pull off a bra and sheer blouse at 63. Mon dieu…j‘adore!

Emma Roberts in Armani Privé
This dress was from Mr. Armani’s second Armani Privé collection that debuted in Paris in July 2005. The nude and pale green silk tulle, crystal encrusted dress with geometric patterns was ravishing against Roberts’ dramatic red locks. And if this look seemed a bit more covered up compared with her Armani Privé from earlier in the evening, know that the high-neck silhouette came with a plunging back.

Brie Larson in Ralph & Russo
This dress was slashed and ruched in all the right places and the forest green color did wonders for Larson’s beautiful complexion.

Viola Davis in Brandon Maxwell and Stella McCartney shoes
What a night for Viola Davis! The actress took home the Oscar and had not one but two red carpet wins.

Kate Bosworth in J.Mendel and Piaget jewelry
It’s no secret that Bosworth knows and loves fashion. This sea green J.Mendel gown might be one of the most beautiful gowns of the entire evening.

Lily Collins in Elie Saab and Forevermark jewelry
Collins has been emerging as one of the red carpets best-dressed and she didn’t let us down at the Oscars. This is a dress that should have been walking at the main event. Everything from the dress to the hair and makeup were perfect.

Sarah Paulson in Ronald van der Kemp, a Judith Lieber clutch, and Karla Welch for Forevermark earrings
Paulson has a seriously good sense for fashion and an adventurous side. Her velvety ’40s-style Ronald van der Kemp was one of the more unusual and exciting choices of the evening.

Rooney Mara in H&M Conscious Collection and Jimmy Choo heels
Can you believe Mara’s dress is from H&M? And from their Conscious Collection, to boot! The off-white pleated georgette look is made entirely of sustainable materials. This is a winner in so many ways.

Michelle Dockery in Roland Mouret, Charlotte Olympia heels, and Bulgari jewelry
The modern elements of this beautiful dress combined with Dockery’s sleek locks and classic makeup were a winning combination.

Karlie Kloss in Naeem Kahn and Roger Vivier clutch
Kloss is 6’2″ and has a body and face that put the bills in her bank account. This dress is another reminder of why Kloss is one of fashion’s biggest success stories.

Hailee Steinfeld in Ralph & Russo
This dress was a less girly version of what Steinfeld wore on the red carpet and it was stunning. With her figure and the dramatic train, Steinfeld should have been in this dress all night long. But hey, why have just one look when you can have two?

Abigail Spencer in Thai Nguyen Atelier
Spencer’s burgundy sequin high-neck mermaid gown was a lovely choice for the fair-skinned, raven-haired beauty.

Kate Hudson in Cavalli Couture
This wasn’t one of Hudson’s more exciting red carpet choices, but it was pretty nonetheless and fit her like a glove.

Georgina Chapman in Marchesa
Who better to rock Marchesa than its co-founder? Chapman is perhaps the best advertisement for her own brand. Harvey Weinstein is one lucky man!

Kiersey Clemons
There’s no word so far on who designed Clemons’ gorgeous gown—the off-the-shoulder cream silk gown was the epitome of Hollywood elegance.
