“Y’s” 20AW Layered tweed double zip jacket

“Y’s” 20AW Layered Tweed Double-Zip Jacket

Introduced in 1972 as the first brand crafted by Yōji Yamamoto, Y’s has always pursued functional, dignified everyday wear that is not swayed by trends—incorporating the structure of men’s clothing into the female form. We are pleased to present a standout piece with a layered design that brings together the structure of different garments into one.

Built into a black-based tweed jacket with fine strands intersecting intricately is a structure reminiscent of zip-up outerwear layered from the inside. It brings together the classic texture of tweed and sporty functionality into a single, cohesive silhouette.

What first catches the eye is not simply the completed shape of a typical tweed jacket. Instead, the silhouette is switched around the waist level, revealing the black body largely from within—a distinctive layered effect.

Because the tweed portion is finished without a collar, keeping the neckline clean, the rich character of the weave stands out. With threads running finely in white and bluish tones on a black base, the fabric looks chic from a distance, yet reveals a complex depth up close.

Inside, a black body with a stand collar featuring ribbing and a double zip is placed, and by layering functional, bomber-like elements onto the neatness distinctive to tweed, the piece is refined into a design that doesn’t quite fit within any established category—very much in keeping with Y’s.

In addition, the front uses a YKK double-slider zip that can be opened and closed from both the top and bottom. This means you can not only keep it fully closed and emphasize the vertical line, but also open the hem to change the volume and how it overlaps with your inner layer. It’s a particularly interesting point that the wearer can adjust the silhouette themselves.

The lower black body expands toward the hem, forming a soft rounded shape reminiscent of shirt tails. Thanks to the difference in length between the shorter tweed portion and the lower section, it creates a clearly defined two-layer structure—more distinct than a simple switch between different materials.

At the cuffs, 100% wool ribbing is used to soften the tweed’s crisp, structured feel like a knit. On the inner circumference of the tweed portion, black piping is run through so that even when worn open, the outline does not become ambiguous—finished with meticulous care.

The material composition is also highly distinctive. The upper body blends wool as the main component with polyester, rayon, acrylic, and nylon, allowing the tweed’s characteristic unevenness and the mixing of colors to be expressed through multiple fibers. Meanwhile, the lower body is primarily wool (58%) and rayon (41%), giving it a smooth drape different from the upper part.

As a 2020-21AW piece bearing the style code YR-Y03-811 and the quality marking MADE IN JAPAN, it uses classic tweed yet does not simply settle into a straightforward, well-behaved jacket. Instead, with a structure that incorporates zip-up outerwear and a long hem into the interior, you can very clearly see Y’s philosophy—one that values the volume created between overlapping layers and the body. The brand’s official explanation of Y’s also emphasizes the sense of air and the volume that form between a person and their clothing, along with cutting, silhouette, and the texture of materials. This piece can be said to be a design that makes that viewpoint easy to understand visually.

Because it brings together elements of a tweed jacket, a bomber-style outerwear, and a long shirt, one of its major charms is that the layered look is completed just by putting it on. Even without frequent layering, it can create a Y’s-like silhouette with depth—an added value that is unique to this standout piece.

We particularly hope you will consider it if you would like to wear classic tweed in a more modern, mode direction, or if you want to vary the look through both material and silhouette while keeping black as the primary color. Since the context of a feminine tweed jacket intersects with the structure of men’s-style bomber outerwear, this is a piece you can enjoy without being bound by gender.

For styling, pairing it with a long skirt or drapey slacks can create a Y’s-like long, vertical silhouette that makes use of the movement of the layered hem. Alternatively, styling it with wide pants or sharp dress pants and letting the jacket itself be the focal point looks equally beautiful. By keeping the inner layer as simple as possible, the switch between tweed and black becomes even clearer. With its built-in structure, it still naturally fits into everyday wear—truly a standout piece.

We would be delighted if you could take this opportunity.
