Kim Kardashian is saddled up for summer.

The reality star soaked up the sun on her Hawaiian vacation in a black Gucci string bikini finished with the house’s gold horsebit hardware.

The price tag on the tiny two-piece? A cool $1,300.

In case the suit was too subtle on its own, Kardashian, 45, added a diamond double-strand belly chain for her day by the ocean. Indoors, she layered on a sheer black bolero and black leggings for a monochrome look.

By the Skims founder’s standards, the body jewelry is relatively modest: In 2023, she turned a Messika necklace set with a 17-carat pear-shaped diamond into a belly chain for Michael Rubin’s Fourth of July bash. At the time, experts told Page Six Style the piece could be worth as much as $3 million.

This latest look is her second Gucci bikini of the getaway; earlier this week, she caught waves in a pink monogram two-piece styled with Chanel shield sunglasses and a bandana.

Boyfriend Lewis Hamilton is along for the trip, along with her daughter Chicago and son Psalm.

Hamilton’s day job has turned into a styling opportunity, too. Kardashian wore a full Gucci wardrobe across three days at the Monaco Grand Prix in June, watching the Ferrari driver from the paddock in horsebit-trimmed flared jeans and matching pumps.

In March, she hit the Vanity Fair Oscar Party in a sequined gold gown pulled from creative director Demna’s first collection for the label, teetering on 8-inch Pleaser platforms.

Gucci swimwear runs in the family; Kylie Jenner modeled an archival spring 2010 cutout one-piece in April, and Khloé Kardashian paired an $820 monogram bikini with faux fur on a ski trip back in 2024.
