Hailey Bieber wears gold breastplate and Belperron jewels at Met Gala

Hailey Bieber’s Met Gala look worked because the jewelry did not sit on top of the outfit. It completed it. In New York City on Monday, May 4, 2026, Bieber arrived solo for the evening’s “Costume Art” dress code in a custom Saint Laurent look by Anthony Vaccarello, built around a gold breastplate and a cobalt blue chiffon skirt.

The effect was less red carpet literalism than wearable sculpture. The breastplate, described as either 24K gold or hammered metal, gave the look its sharpest line, while the bright blue skirt pulled the sheen into something more fluid and modern. Without Justin Bieber at her side, the spotlight stayed where the styling wanted it: on the interplay between hard metal and soft fabric, body and drape.

The jewelry made the formula precise. Bieber wore Belperron pieces that echoed the bodice rather than competing with it, including gold leaf earclips, a gold Toi et Moi ring, and a Bourrelets ring set with sapphire, emerald and gold. Those choices mattered because they introduced texture and color into a look that could have read as all surface. Instead, the stones and the leaf shapes softened the metal’s severity and gave the outfit a vintage-coded elegance.

Belperron’s Virgin Gold collection has long depended on that tension. The house says Suzanne Belperron frequently worked in 22-karat gold, hammered and burnished to create a raw finish, a detail that explains why the jewelry felt so right against Bieber’s polished Saint Laurent silhouette. The Cabochon Leaf Earclips, Toi et Moi Ring and Bourrelets Ring in Sapphire and Emerald all carry that same language of tactile gold and richly saturated color.

That balance is the real lesson in Bieber’s look. Gold does not have to mean heavy or rigid, and a red-carpet breastplate does not need to read like armor. When sculptural gold is paired with vintage-inflected shapes and a few colored stones, the result feels less like costume than composition. It was the sort of styling move that makes an arrival look instantly shareable, because it translated the night’s theme into something clear: jewelry as garment, and gold as the element that made the whole image hold.
