Ariana Grande in vintage Badgley Mischka plaid gown at Focker In-Law premiere

Ariana Grande has gone back into the archives again, this time for the New York premiere of Focker In-Law. The pop star and Oscar-nominated Wicked actress plays Olivia Jones, Henry Focker’s girlfriend, in the new comedy, and she arrived at the Beacon Theatre on Wednesday night in a vintage 1990s Badgley Mischka gown, styled by Law Roach.

The dress is a pale silver-grey plaid in a crisp, glossy-looking fabric, with skinny spaghetti straps and a scooped neckline. The fitted bodice is covered in little white flowers that thin out towards the waist, and below that there’s a gathered, dropped seam and a huge skirt that sweeps the floor. Very ladylike, very sweet, and a fair way from the sheer, dramatic gowns she’s been in lately. For another of her big gown moments, have a look at Ariana’s 2018 Met Gala gown.

She kept the jewelry small, with a pair of little diamond earrings, and let the hair do the talking. It was slicked back into a sleek bun with a cream ribbon tied in and left trailing down the side, which gave the whole thing a slightly vintage, ballet-school feel. Makeup was icy pink shimmer on the lids and a glossy, mocha-brown lip.

She wasn’t alone, either. Boyfriend Ricky Alvarez joined her on the carpet for their first official red carpet appearance as a couple, dressed down in a black blazer, white shirt, jeans and brown shoes. They posed with his arm wrapped around her waist, and she leaned right into him.

Focker In-Law is the fourth film in the Fockers series, with Ben Stiller and Robert De Niro back, and it arrives in theaters on November 25.
