While genderless styles are gaining attention, this fall's men's fashion is showing a marked return to masculinity and style. At Pitti Immagine Uomo, held in June, fashionistas were often seen wearing three-piece suits reminiscent of British gentlemen alongside classic Italian suit styles, suggesting a return to menswear will be a hot topic this season.

International Luxury on the fourth floor of the Isetan Shinjuku Men's Building offers a new way to enjoy suits in its pre-fall collection, reinterpreting the military roots of menswear with minimal details and clean fabrics.

We would like to introduce a luxurious three-piece style, developed as an original Isetan Mitsukoshi (ONLY MI), "interpreted for customers who seek eternity." Giorgio Armani, celebrating its 40th anniversary this year, is offering a three-piece suit with a short jacket and slim pants with a 19cm leg opening, available exclusively at Isetan Mitsukoshi. This suit (¥330,000) features a two-button peak lapel, a lightweight silhouette with no interlining, and a V-neck vest (¥95,000), creating a modern businessman style that fuses Italy and New York. While the material may appear plain at first glance, its lustrous melange weave makes it perfect for evening wear. Brunello Cucinelli, which offers a fashionable look based on high-quality materials and artisanal techniques, offers a three-piece suit (¥500,000) paired with a British-style double-breasted vest (¥160,000). The soft, lustrous Batavia wool is truly luxurious. Enjoy a sophisticated suit style by pairing a shawl collar vest alone with pants and a jacket.

Salvatore Ferragamo is offering a check suit (¥350,000), a popular choice this season, exclusively at Isetan Mitsukoshi. This contemporary three-piece style combines a "CITY FIT" silhouette, featuring a length two centimeters shorter than a regular suit, slim lapels, and slim pants, with a vest (¥102,000). Complete the look with a pair of double monk boots (¥116,000) featuring a sleek, rounded toe for an urban look.

CARUSO was founded in Parma in 1958 by Raffaello Caruso, a former Neapolitan tailor. Umberto Angeloni, who built Brioni into a world-renowned fashion house, oversaw the relaunch of this long-established brand. Since becoming CEO of Caruso in 2009, he has been creating a new urban classico style through handmade production and state-of-the-art equipment. This time, he proposed a navy houndstooth micro-check three-piece suit (230,000 yen) that appears plain from a distance. The soft feel of the unconstructed jacket, known as the "Aida model," is uniquely tailored to the Japanese body type for a comfortable fit.

STILE LATINO was founded in 2004 by Vicenzo Attolini, who inherited the name of his grandfather, a legendary tailor at a Naples tailoring company. As the name suggests, the "Latin" design is a classico style befitting the eldest son of the Attolini family. This three-piece suit (330,000 yen) features striking wide peak lapels, and the double-breasted vest creates a truly stylish breastline. Cesare Attolini, a renowned Neapolitan tailor and former tailor at London House, inherited the Attolini brand. Since its founding in Naples in 1930, the brand's exceptional handcraftsmanship and timeless cuts have remained unchanged, resulting in unparalleled comfort. The brand's signature "S model," featuring a high, form-fitting neckline paired with a shawl collar vest, creates the ultimate Neapolitan three-piece suit (¥660,000). Launched last year under creative direction from Massimo Piombo in partnership with the Kiton Group, MP di Massimo Piombo's aristocratic finish is crafted from the finest materials and features exquisitely balanced details. A three-piece suit (¥290,000) in soft wool with a charcoal gray herringbone and stripe pattern is a masterpiece that strongly embodies the brand's aesthetic.
