'OUR WACOAL' and 'YANUK' Announce First Collaboration: Releasing Cup-in Wear Tailored for Denim Styling

Wacoal Corporation (Headquarters: Kyoto City, Kyoto Prefecture; President and Representative Director, Executive Officer: Keisuke Kawanishi) has announced the first collaboration between its fashion brand, 'OUR WACOAL,' and the denim brand, 'YANUK.' Three new types of cup-in wear will be available starting Thursday, June 4, 2026, at select retail stores nationwide and e-commerce sites, including the Wacoal Web Store.

'OUR WACOAL' is a brand that proposes items for individualistic styling, centering on 'cup-in wear' that fulfills the roles of both clothing and underwear in a single garment. Meanwhile, 'YANUK' is a denim brand manufactured in its own factory in Okayama Prefecture, widely supported by fashion-loving women for its beautiful silhouettes and comfortable fit.

This collaboration was realized through a shared resonance between both brands' 'authentic commitment to materials and silhouettes' and their 'attitude towards craftsmanship.' By combining 'YANUK's' desire for consumers to 'enjoy denim fashion comfortably even in the hot summer' with 'OUR WACOAL's' philosophy of cup-in wear that 'achieves both comfort and a good look in a single piece,' they developed cup-in wear specifically intended to style perfectly with denim.

The lineup features three styles: the 'Cup-in Bare Camisole,' the 'Cup-in Bi-color Camisole,' and the 'Cup-in Pile Tank Top.' Based on the designs of popular camisoles and tank tops from 'OUR WACOAL,' the products pursue colors and materials typical of 'YANUK' with an awareness of their compatibility with denim. 'YANUK's' original embroidery is applied to the back and hem, creating a design unique to this collaboration.

Functionality is also a key focus. Utilizing underwear manufacturer technology, the integrated left-right cups and free-cutting under-design achieve a natural and beautiful bust silhouette even without underwires. As cup-in wear that can be worn as both clothing and innerwear, it allows consumers to enjoy summer denim styles with ease.
