Pair with Matching Trousers
Styled together with the Slim Tapered French Work Chino Trousers made from the same fabric, it works perfectly as an elegant set-up for refined off-duty looks.
Twill with Depth and Lightness
This stretch fabric captures the rugged essence of French workwear while carrying a refined tone.
Finished with JAPAN BLUE’s original “shady” process, it delivers rich color depth and a soft hand feel. Unlined and lightweight, the piece is comfortable not only for fall and winter but also as a transitional layer in spring.
The seams are finished with careful piping, ensuring refinement even where unseen.

Designed with notched lapels and two-button closure—timeless elements interpreted through a contemporary lens.
Flap pockets can be styled tucked in or out, balancing utility with a clean, sophisticated look.
Slim, Modern French Workwear
A sharp, tailored silhouette that remains elegant. Compact through the arms and body, it reflects a contemporary sensibility. The clean lines give an intellectual, urban impression simply by layering it on. A versatile piece designed for layering in cooler months as well.
