UNDER Y’s

Y’s introduces UNDER Y’s, a collection that rethinks Y’s garment-making from the layer closest to the body.

The collection will be available at Y’s stores throughout Japan and the official online boutique from Friday, August 14, 2026.

UNDER Y’s is a new base-layer collection designed to support the Y’s wardrobe.

The name "UNDER" represents more than simply garments worn beneath clothing. It also reflects the unseen foundation that supports the structure, comfort, and wearability of a garment.

Created not to be seen but to become part of everyday life, the collection combines exceptional comfort that moves naturally with the body and the refined silhouettes unique to Y’s.

The lineup includes nine styles: Tank Top, High-Neck Sleeveless, Crew-Neck Short-Sleeve, Crew-Neck 3/4-Sleeve, Crew-Neck Long-Sleeve, High-Neck Short-Sleeve, High-Neck Long-Sleeve, Short Leggings, and Leggings.

Crafted from a supple, soft-touch fabric with excellent stretch, each piece is designed to move comfortably with the body. The material also offers UV protection with a UPF 50+ rating.

The packaging is made from the same paper material as the signature Y’s shopping bag, creating an original package designed as an extension of the product itself.
