12 hidden details you may have missed in celebrity outfits at the 2023 Oscars

Halle Bailey wore a turquoise tulle gown in a nod to her upcoming role in Disney's remake of "The Little Mermaid."

Bailey appeared in a strapless, turquoise tulle gown with a corset top and full skirt by Dolce & Gabbana.

"I was excited to wear this pouffy dress to go into the fairy-tale world and give princess for one day," Bailey told E! News. "I'm loving it."

Hong Chau's pink Prada dress included a custom collar as a nod to her heritage.

"I asked them if they could add a little Mandarin collar as a little shout out to my roots and they were happy to oblige," Chau, who was nominated for best supporting actress for her role in "The Whale," told E!. "So it just feels like a really modern dress. I feel beautiful in it. But I also feel like I can move and I'm nimble so it feels very me."

The dress also had a back cutout and feathered train.

 

Florence Pugh's Valentino look featured black shorts with pockets.

The shorts were concealed beneath her grey strapless gown with oversized, off-the-shoulder sleeves.

Pugh voiced Goldilocks in "Puss In Boots: The Last Wish," which was nominated for best animated feature film.

Harry Shum Jr.'s tuxedo jacket included a sash reminiscent of a traditional Japanese obi.

The "Everything Everywhere All At Once" star described his Adeam look as "East meets West," according to The New York Times.

Malala Yousafzai attended the Oscars in a shimmering silver Ralph Lauren gown that included a built-in headscarf.

Yousafzai, who produced the Oscar-nominated documentary "Stranger at the Gate," told Variety that she was most excited to see Rihanna.

"Rihanna is such a powerful, incredible woman," she said. "She has inspired so many generations of girls and she is just stunning and she sings so beautifully, so I will be stunned to see her performance."

Designer Monique Lhuillier created Chloe East's black strapless gown with sustainable fabric.

The bodice of East's dress was recycled from Monique Lhuillier's Autumn 2019 Collection,  according to Innovation in Textiles, and the rest of the look was made with biodegradable Tencel fabric made from plants.

East wrote on Instagram that she was "very excited to be supporting sustainable fashion" as an ambassador of The Academy's Red Carpet Green Dress initiative.

Bailey Bass also wore an eco-friendly gown designed by Zac Posen Couture.

Bass' white halter dress with billowing sleeves was made with sustainable Tencel fabric. She paired the look with Nicole Rose jewelry and a Kate Spade bag.

"CODA" star Troy Kotsur wore a pin in the shape of the American Sign Language sign for "I love you."

Kotsur, who won best supporting actor last year, presented this year's category with fellow 2022 winner Ariana DeBose.

James Hong paid tribute to "Everything Everywhere All At Once" with googly eyes on his blue bow tie.

In "Everything Everywhere All At Once," Ke Huy Quan's character, Waymond, regularly sticks googly eyes on items, much to the annoyance of his wife, Evelyn, played by Michelle Yeoh.

Hong, 94, who attended the Oscars for the first time, also wore a black tuxedo and royal-blue shirt.

Daniel Kwan's red suit with gold detailing on the arms and "PUNK" written across the back also referenced "Everything Everywhere All At Once."

Kwan's red suit paid tribute to the red sweater that Evelyn (Michelle Yeoh) wears at the Lunar New Year party in "Everything Everywhere All At Once." The film swept the Oscars, winning a total of seven awards including best picture.

Melissa McCarthy's Christian Siriano dress was entirely remade days before the Oscars after the designer's studio flooded.

McCarthy's red gown made a statement on the champagne carpet with its high neckline, shoulder pads, and full, ruffled skirt.

Siriano said he had to remake the dress just days before the ceremony after a pipe burst in his studio, joking in an interview with E! that the experience was "traumatizing to my life."

"I wasn't gonna say anything about what really happened because I don't want the actress who's wearing something to know that her dress was fully remade," he told E!.

Ruth E. Carter matched her acceptance-speech notes to her yellow strapless gown.

Carter won her second Oscar for best costume design for "Black Panther: Wakanda Forever." She previously won the same award in 2019 for her work on the first "Black Panther" film, making her the first Black woman to win two Academy Awards.
