Blue refabric
Built on a concept of high-quality Japanese fabrics and a commitment to authentic craftsmanship. Originally produced for many years as a ROCOCO exclusive line of JAPAN BLUE JEANS, it relaunches in 2026 under the name “Blue refabric.” Production centers around partner factories of JAPAN BLUE JEANS. The name combines “Blue” — representing Japanese denim — with “Refabric,” a coined word blending Republic and Fabric. Inspired by the idea of a “Blue Republic,” the brand honors Japan’s textile heritage while creating garments that bring out the individuality of the wearer.

The fabric uses duck cloth with a naturally irregular texture. By omitting a lining, it is designed for wear across multiple seasons.

The paraffin finish adds light water repellency and resistance to dirt, enhancing practicality.



The paraffin coating, created by infusing wax into the fabric, develops unique aging over time, including chalk marks—where creases and folds appear lighter—and a natural fade that adds character.





Comfortable construction
The neckline is designed to open cleanly and maintain a balanced shape, whether buttoned or unbuttoned.



The shoulders feature a split raglan design—appearing as a set-in sleeve from the front and a raglan from the back—combining a structured look with ease of movement.



A basic chest pocket is placed on the left, while large patch pockets at the waist provide practical storage.



An inner pocket on the right chest adds convenience.



Structured for comfort and form
The body is constructed using a three-panel pattern (front, side, and back), creating a dimensional, clean silhouette. It offers a smart appearance while remaining comfortable and unrestricted to wear.
