Junya Watanabe has consistently toyed with the legendary designs of fashion's most enduring labels, from the inventors of jeans to heritage British shoemakers. And the latest addition to its ever-strong collaborative output is Watanabe turning its focus to the oldest clothing label in America.

The Japanese designer has used staples from the U.S.'s oldest apparel house, Brooks Brothers, as a canvas on which to splatter experimental nods to vintage workwear and military gear.

This materializes into Brooks Brothers' traditional sack blazer, a staple in preppy menswear, being dressed with a camouflage lining and a hardwearing cotton polyester gabardine outer. It's a fabric choice also added to matching chino pants, long-length shorts, and dog-ear collared, harrington-style jacket.

Watanabe's rugged interventions offer this quartet of menswear staples an extra sturdy, shape-sustaining fit almost as durable as some of the functional gear it's inspired by. These pieces blend the worlds of modern American prep and equally all-American military wear.

The capsule collection is anchored by a Brooks Brothers classic, the white oxford shirt, this time made of washed Supima cotton oxford fabric.

Tragically, as seems to be the case with a good lot of likeminded releases (think Brooks Brothers x N.HOLLYWOOD), these clothes are part of upcoming Japan-only rollouts available now from select retailers. Tough luck for those of us who are stateside, save for those versed in proxy services.
