Junya Watanabe's COMME des GARÇONS JUNYA WATANABE MAN held its Spring/Summer 2018 collection show in the corridors of Jacques Ducourt High School, located on the border between the 9th and 18th arrondissements of Paris. "A collection for stylishly wearing serious workwear." While '70s soul music, including Marvin Gaye and the Spinners, reverberated, the show featured numerous collaborations with American workwear brand Carl Hart. Various approaches were used, including customizing Carl Hart pieces, creating pieces using fabrics provided by Junya Watanabe Man, or creating pieces using Carl Hart's own fabrics using patterns created by Junya Watanabe Man. There was also a Carl Hart-inspired blouson jacket, blurring the line between collaborations and collaborations.

The innerwear is coordinated with a shirt by London's Turnbull & Asser, achieving a mix of blue and white colors even in workwear. Continuing from the previous season, collaborative blousons with The North Face and collaboration items with British outdoor brand Karrimor are also seen, demonstrating a commitment to authenticity and not just "style." Finally, a model appeared wearing a T-shirt featuring the Levi's logo.
