In Rihanna’s world, business mode and party mode are one and the same. The music mogul leaned into the baggy suiting trend to celebrate her 37th birthday in Los Angeles last night by dressing up in a full suit and tie. Naturally, her just as stylish partner A$AP Rocky did the exact same.
Instead of the typical party dress, Rihanna went with a double-breasted suit coat from Saint Laurent’s celebrity-favorite spring 2025 collection. She paired her tailored jacket with black office pants, knife-point stilettos, and a leather shoulder bag. Rihanna leaned into her businesswoman bonafide by accessorizing her white button-down with a striped burgundy tie.
According to stars, full suits and ties aren’t just for office cubicles. Like Rihanna, most are looking to Saint Laurent’s spring 2025 runway offering for inspiration. Earlier this week, Jennifer Lopez wore a chocolate brown coat from the collection (though sans tie) to do business in Dubai. Both Ariana Grande and Elle Fanning picked out nearly identical Saint Laurent looks this awards season as did Nicole Kidman. The latter actor went against the typical red carpet gown at the 2025 Critics Choice Awards when she wore an oversized Saint Laurent look to the event.
Of course, it’s one thing to sport a classic suit to walk the red carpet or attend a movie screening. But it’s an entirely different thing to chose the tailored look over typical party clothes like Rihanna did last night. The mogul could have just as easily went with one of her signature statement coats or something like the archival LaCroix she wore late last year to dance in. The full suit is back.
