Y's for men and MASSES collaborated for the first time in the 2025 Autumn/Winter season, creating a collection that brilliantly blended their respective creations and made a significant impact on the market.

The 2026 Spring/Summer season marks the second collaboration between the two brands, following their successful partnership in the previous season. The collection brings together a series of suits showcasing Y's for Men's expertise in diverse material usage, and pieces rooted in Mathis's signature reinterpretation of vintage styles and original textile designs, creating a collection that enables a kind of "early 90s-esque look." For those familiar with that era, the style resonates deeply, while for those unfamiliar with it, the combination of disparate items feels fresh and has generated a surprising amount of empathy. The 2026 Spring/Summer season is undoubtedly attracting even more attention and momentum than the previous season.

The "early 90s style" referred to here is nothing less than a mix of "mode x vintage." In the 90s, a style that skillfully blended vintage pieces with high-fashion items was commonly seen among some stylish young people. This type of style, which is unparalleled in the world, was in a sense uniquely Tokyo, and it seems that many people tried it. Because Tokyo surpasses other cities in terms of information, goods, and population, the number of clothing and brands concentrated there is enormous, and it can be said that this unique style was only possible because all genres were blended together.
The true essence of this collection lies in its ability to create a style that closely resembles this feeling. It enables alternative styles that transcend genres and categories, such as pairing a dressy suit with an open-collar shirt made of abstract, patterned textiles, or styling an M-65 coat with a stand-collar shirt and slacks.

The pop-up shop featuring the full lineup of the collection created by Y's for Men x Mathis will finally launch on Wednesday, March 18th at Isetan Shinjuku Store, Men's Building 6th floor, Men's Creators. Based on the world view showcased in the lookbook, we encourage you to find your own style and balance.

The Y's for Men x Mathis 2026 Spring/Summer collection conveys the joy of dressing stylishly through its unique balance and color combinations. From slightly formal items like suits to casual pieces like denim and Hawaiian wear, the way they are combined can create a sophisticated and refined masculine look. As is immediately clear from the lookbook, what emerges from the harmonious blend of high fashion and street style is none other than the "early 90s Tokyo" aesthetic that some people practiced during that era.

♢STYLE①：SHRINK SERGE SET-UP

One of the signature materials of the Y's for Men x Mathis collection is felted fabric. For the SS season, they used a lightweight, sheer fabric and paid close attention to the washing process, resulting in a unique texture. Because the set has a casual design, pairing it with a graphic T-shirt underneath and sneakers in the same color as the set creates a perfectly relaxed look.

♢STYLE②：PILE SET-UP

This stylish outfit centers around a pile fabric set in a deep navy color, paired with an open-collar shirt as an inner layer. While the items are made from casual materials, the pattern and silhouette have been meticulously crafted down to the millimeter, allowing for a dressy feel as well. The inner shirt is made from a finely woven dobby stripe fabric, giving it an undeniably high-quality texture.

♢STYLE③：LINEN CLOTH SET-UP

This linen set-up catches the eye with its light texture and subtle sheen. Y's for Men x Mathis continues to offer set-ups in each collection, but this item is a highlight piece for the 2026 SS season. The inner shirt, which features the same lightning bolt pattern as STYLE② but is finished on a black base, has the pattern expressed through discharge printing, and the beautiful cut of the open collar is also outstanding.

♢STYLE④：RIGID DENIM SET-UP

This denim set-up was made possible only through collaboration with Mathis, who has a deep understanding of vintage clothing. The jacket, made from a slightly thick 14oz denim fabric, is a 2nd type, while the bottoms have a 1930s feel with a back cinch. The exquisite silhouette elevates these workwear-derived items into a sophisticated look. The meaning behind modifying the weak points of vintage pieces becomes instantly clear the moment you put it on.

♢STYLE⑤: HAWAIIAN SET-UP

These Hawaiian shirt and pants are made from rayon, capturing a drape that closely resembles vintage styles. The impactful colors and patterns feature a unique textile design reminiscent of "volcanoes and dead trees," often seen in rare vintage pieces. There's no need for any elaborate styling; this item is best worn as a set. Both the long-sleeved shirt and shorts, and the short-sleeved shirt and shorts, offer a powerful and stylish look.

♢STYLE⑥：SOUVENIR BLOUSON

This souvenir jacket, famously produced during the Vietnam War in the 1960s and 70s, stands out from the rest with its unique slub-textured outer fabric, dragon motifs reminiscent of children's vintage jackets on both sleeves, and a glossy, smooth acetate lining. A stand-collar shirt is paired underneath to add a touch of modern style.
