The "Emilia Pérez" star was undoubtedly among the best-dressed stars at the 2025 Oscars, in a rose-gold gown from Ralph Lauren.

When she arrived at the after-party, she topped the look with a shimmering black number from Armani Privè and a thick diamond choker that tied the look together.

The custom Christian Dior look that Barbaro wore to the 2025 Oscars missed the mark.

But that wasn't the case for the custom Dolce & Gabbana gown she changed into for Vanity Fair's party.

The strapless dress, crafted from cream-colored fabric and embellished with sparkling silver strings, fit her perfectly and looked classic at the after-party.

Zegler was a vision in her cream-colored halter gown. The neutral piece had a chest cutout, ruffles all over its bodice, and a lace skirt that flowed around her feet.

She also complemented the look perfectly with an updo hairstyle and long earrings.

Madison evoked old Hollywood glamour for her after-party appearance.

She wore a strapless black gown with a plunging V-shaped neckline, a wrapped bow belt, and a full skirt.

The Oscar winner also draped a scarf around her arms and donned a statement ruby necklace.

After wearing a velvet red dress that wasn't tailored well to the Oscars, Ryan looked chic at the Vanity Fair after-party in a semisheer dress.

The tan piece was sleeveless, had a beaded collar, and was embellished from top to bottom with delicate sparkles. The actor wore the look with rosy makeup and a diamond bracelet.

Jenner sat in a custom Miu Miu dress next to her boyfriend, the Oscar nominee Timothée Chalamet, at the 2025 Oscars. She then attended the Vanity Fair after-party in a new gown designed by Ashi Studio.

The corseted design was strapless, with a sheer illusion bodice and lace skirt.

It fit Jenner like a glove and made for the perfect edgy look with her dark, wavy hairstyle.

Sennott's sparkly pink dress for the Oscars wasn't her best, as the sequins didn't match the glamour of the red carpet. It didn't help that her black tights looked out of place.

But the black high-low gown the "Saturday Night" star changed into for the after-party struck the perfect tone.

The gown's plunging halter neckline gave way to a dropped-waist bodice, and the pleated fabric on the skirt made the dress look like it spilled onto Sennott's body. It created a fun and dramatic look.

Jones chose a custom Coach dress for her Oscars debut, which had sparkles on the skirt as well as a daring slit. It was a solid look, but it didn't stand out from the pack.

She changed into a strapless gown that leaned into the butter-yellow trend for the after-party. The architectural detailing on the strapless corset bodice contrasted with the ruching on the skirt, which had a slit, just like her first dress.

The colorful ensemble was the perfect continuation of the fashion story Jones started earlier in the night.

Lisa swapped out the menswear look she wore to the awards ceremony for a custom Miss Sohee dress that had a gothic feel.

The base of the K-pop star's look was a sheer black bodysuit with a high neckline and intricate lace. The strapless dress featured a sweetheart neckline, and the skirt bubbled around her hips before flaring inward for an exaggerated hourglass shape. She accessorized the look with wet hair and diamond jewelry.

The dress was stunning, and Lisa amped the look with edgy styling.

The "Heartstopper" star's Oscars outfit had too much going on, from the jacket with tails to the sparkly vest he wore with it.

His after-party look was much simpler — and much more stylish. He wore a tuxedo shirt with no tie or jacket, pairing it with a cummerbund and wide-legged pants.

A gold brooch on his chest elevated the party-ready look.

The tennis star wore two colorful Miu Miu gowns to celebrate the Oscars, but her second look was stronger than the first.

The yellow dress she wore to the awards ceremony looked a bit dated because of its thick straps and large, sparkly embellishments that covered it from head to toe.

The green gown Gauff changed into for the after-party felt fun and fresh in comparison. The sheath dress had spaghetti straps. Gems were embroidered onto the bodice in the shape of florals that cascaded down the garment. A circular cutout in the back gave the gown a sexy edge.

Erivo looked stunning at the Oscars, celebrating her character Elphaba from "Wicked" in a custom Louis Vuitton gown.

But her dress for the after-party felt like a celebration of Erivo herself, which was a welcome change from the rest of her awards season looks.

Erivo's Vivienne Westwood gown was made of a gauzy gray fabric that crisscrossed over her body to form a mini dress. The fabric spilled into a floor-length train on one side, and a black bow sat on one of Erivo's shoulders and her waist.

She carried a heart-shaped bag and wore gothic-style jewelry with the outfit, creating a look that was both whimsical and sexy.

Gadot wore red Prada dresses to both the Oscars and the after-party, but the sheath dress she changed into was more interesting than the satin ball gown she wore to the show.

Sparkly black beading adorned the dress from head to toe, bringing texture to the simple silhouette.

Gadot wore a red scarf around her neck, mixing old Hollywood glamour with the more modern ensemble.
