Rosalía bares her cotton underwear for SKIMS's first bilingual campaign

SKIMS announced Spanish singer-songwriter Rosalía as the face of the brand's latest cotton collection.

The collaboration, which launched Monday, marks a historic milestone for the brand as it embarks on its first bilingual campaign.

"I love SKIMS. They are so comfy and make me feel very sexy at the same time," Rosalía said in a news release for the partnership.

"Rosalía's willingness to push the boundaries and experiment with her music and personal style has been a huge inspiration for me. This campaign is all about the energy and confidence that she brings to the world," said SKIMS founder Kim Kardashian. "I'm especially excited that she's wearing pieces from our best-selling Cotton Collection – they're classic, cool and breathable everyday essentials that everyone feels good in."

In teaming up with Rosalía, SKIMS hopes to expand its global reach and bring its "solution-based" styles to a larger audience.

The campaign, shot by Donna Trope, features Rosalía in SKIMS underwear, including their deep-plunge bralette, fitted briefs and more.

This is the Grammy-award winner's first fashion partnership.

"I'm so excited that I finally got the chance to collaborate, especially in their Cotton Collection which is my fave," she said.

Fans have been showing their excitement about the collaboration on Instagram.

"This is perfect," wrote one user.

"La Rosa killing it!" shared another.

SKIMS has been known to make headlines heads with its star-studded collaborations, including campaigns with Megan Fox and Kourtney Kardashian, as well as supermodels Heidi Klum and Tyra Banks.
