The film's lead, Constance Wuchanneled Old Hollywood in a silver bedazzled off-the-shoulder Ralph & Russo couture gown that featured fringe detailing on the sleeves. She also rocked Sophia Webster heels and some hand-crafted Lorraine Schwartz jewels made just for her. And though she got to wear lots of designer duds on the set, Wu told ET's Lauren Zima at the premiere that she used her film paycheck for a different kind of splurge.
"I bought a house!" she told ET. "A house that I love. It's beautiful."
Her co-star and on-screen love interest, Henry Golding, looked suave in a baby blue Tom Ford suit jacket, white button-up shirt, black bow tie and black slacks. He was thrilled to be dressed by the famed menswear designer.
"Tom Ford is the pinnacle of menswear, and I'm honored to be dressed by him," Golding said.
Michelle Yeoh looked stunning in a black tiered Armani Privé dress with purple rhinestones on the hemlines. But she was more excited about her dazzling accessory.
"You should look at this Crazy Asian watch!" she insisted. "It has a flower that blossoms [on the hour]. It's Richard Mills. It costs $1.8 million."
Awkwafina turned heads in a silk long-sleeve blush ball gown by Reem Acra, which she paired with a red clutch and David Webb Jewels. She couldn't quite believe her luck when talking to ET.
"Check it out, I used to shop at Claire's at the Queens Center Mall, bro, but then I've got a Reem Acra dress and Giuseppe shoes," she gushed.
Victoria Loke was a vision in a yellow Preen By Thornton Bregazzi creation with silver strappy heels.
Adding some sparkle and shine to the green carpet was Gemma Chan in a gold-and-silver sequin Oscar de la Renta strapless frock. She told ET that her silver bag "fits quite a lot," adding that she was carrying her phone, some chewing gum, and lipstick to the premiere. And though she rocks a lot of million-dollar jewels in the film, Chan admitted she was quite as calm and collected as her character.
"I was a bit nervous I have to say," she noted. "I was a little worried that I might just turn my head violently and then an earring might fly off that would be $2 million flying away."
Sonoya Mizuno oozed elegance in strapless black dress with ruffles.
Kris Aquino looked regal in a bright yellow creation, while Fiona Xie opted for a fierce black tulle gown.
Meanwhile, Carmen Soo and Jing Lusi went with artsy multi-patterned designs for their red carpet moment. Lusi chose a Fabiana Milazzo design.
The Crazy Rich Asian men didn't hold back when it came to their fashion, either. Author Kevin Kwan and Jimmy O. Yang opted for snazzy blazers. Yang looked sharp in a yellow ESQ Clothing suit jacket, while Kwan sported Etro.
Nico Santos arrived in a subtle blue suit and added a splash of color with a multicolored handkerchief.
Meanwhile, Ronny Chieng kept things classic in an all-black tuxedo with a white dress shirt and black bow tie.
