Katy Perry wears vintage Lanvin to Tribeca premiere, with Justin Trudeau

Katy Perry used Tribeca to do what red carpets are increasingly rewarding: wear a look with history, shape and restraint. For the premiere of Katy Perry: The Lifetimes Tour - Live From Paris, she stepped out in a vintage Lanvin spring 1987 gown that felt intentionally throwback, not costumed, with just enough polish to suit a film festival crowd.

The dress was a crisp white sleeveless number with thick halter-style straps, spiral rosette appliqués and a gathered waist that opened into an A-line skirt. It had the kind of clean, architectural line that makes vintage Lanvin feel especially modern again, the sort of collector piece that carries the house’s old-world refinement without looking trapped in a museum case. Perry kept the styling spare, adding a vintage white gold diamond ring from Saidian Vintage Jewels and wearing her hair in a bun with soft makeup, which let the dress do the talking.

That Lanvin choice lands with extra interest because the house is entering a new phase. Barbara Werschine joined as chief executive officer in May and is now working with artistic director Peter Copping, a pairing that puts fresh pressure on Lanvin’s archive to look relevant rather than merely nostalgic. Perry’s gown, with its Grecian-leaning ease and precise construction, made a strong case for why that archive still has plenty of life left in it.

The setting mattered too. Tribeca’s 2026 festival ran from June 3 to 14 and marked its 25th anniversary, turning the OKX Theater into a particularly sharp backdrop for this kind of refined vintage dressing. The premiere itself was for a 119-minute concert film shot in November 2025 with 60 cameras, a format Tribeca has positioned as immersive and intimate at once. That blend of spectacle and closeness mirrored Perry’s outfit perfectly: polished enough for a premiere, intimate enough to feel personal.

The evening widened beyond fashion when Justin Trudeau joined Perry on the carpet, with the two posing closely for photos in what WWD described as their red-carpet debut as a couple. Trudeau, the former prime minister of Canada, wore a black slim-fit tuxedo jacket, white shirt, black loafers and black socks, a dark counterpoint to Perry’s all-white look. Together, they made the Tribeca premiere read less like a standard celebrity arrival and more like a neatly staged cultural moment, where a vintage Lanvin dress and a new public pairing carried the same message: retro glamour is back, and it looks best when it is worn with control.
