Katy Perry Wore a Vintage Lanvin SS87 Gown at the 2026 Tribeca Festival With Justin Trudeau

Katy Perry turned heads at the 2026 Tribeca Festival in New York City, where she made her highly anticipated red carpet debut alongside Justin Trudeau. The singer, songwriter, and global pop superstar looked radiant as the pair posed together, appearing relaxed, happy, and completely at ease in front of the cameras.

For the occasion, Perry chose a remarkable vintage Lanvin gown from the Spring/Summer 1987 collection, proving once again that fashion's past often delivers some of the most memorable red-carpet moments. The white gown featured elegant Grecian-inspired draping that skimmed the body beautifully, creating a timeless silhouette that felt both classic and modern.

What truly set the dress apart were the signature cone-shaped embellishments positioned at the neckline and waist. These sculptural details gave the design a distinctive retro character while highlighting the craftsmanship that made vintage Lanvin such a celebrated name in fashion. The gown's clean lines and fluid construction balanced the dramatic accents perfectly, resulting in a look that felt sophisticated rather than overstyled.

Katy paired the archival dress with pointed white heels that subtly peeked out beneath the hem. Her jewelry remained understated, with delicate earrings and rings adding just enough sparkle without distracting from the vintage design.

For beauty, the singer opted for soft glamour. Her dark hair was styled in an elegant updo with face-framing tendrils left loose around the front, creating a romantic finish. Fresh makeup, rosy cheeks, and softly defined eyes completed the effortlessly polished appearance.

While the vintage Lanvin gown certainly commanded attention, much of the buzz surrounded Katy and Justin Trudeau making their first official red carpet appearance as a couple. Together, they created one of the most talked-about moments of the festival, blending Hollywood glamour with a surprising new romance.
