Blue refabric / GL3 Selvedge Denim Semi-Wide Tapered Pants

Blue refabric
Built around a commitment to high-quality Japanese fabrics and dependable craftsmanship.
For many years, the project was produced as a ROCOCO-exclusive line with Japan Blue Jeans, before being relaunched in 2026 under the name "Blue refabric."

Production is centered around partner factories of Japan Blue Co., Ltd. The name combines "Blue," representing Japanese denim, with "Refabric," a coined term blending Republic and Fabric. Under the image of a "Blue Republic," the brand respects Japan's proud textile culture while creating clothing that brings out the individuality of the wearer.

Centered mainly on premium denim from Okayama Prefecture, each piece is carefully made at trusted factories in Japan. The brand pursues minimal yet distinctive design that highlights the natural texture and character of the fabric.

From Japan to the world. Blue refabric presents a new standard inspired by Japan's rich textile heritage.









Its Irregularity Is Exactly What Makes This Denim Special
The warp uses substantial Zimbabwe cotton, while the weft is made from a proprietary blend of several American cottons.

Slow weaving on the GL3 creates an irregular texture across the surface, while the uneven character of the weft becomes even more apparent when viewed from the reverse side. When the hems are rolled up, the rugged character of the fabric becomes a subtle visual accent.




The fabric is also finished with as little post-processing as possible, avoiding treatments such as singeing, sanforizing, and anti-twist processing that would normally make the cloth more uniform. Woven at approximately 14.7oz, the fabric is made into the finished garment and then given a one-wash treatment, allowing it to shrink and develop a dense, substantial feel equivalent to roughly 15oz.

Because the fabric intentionally retains its natural irregularities from the start, the raised areas gradually fade with wear, creating a unique character for each wearer. Rather than being complete when new, this is denim designed to evolve with wear and become truly your own.







The front uses a practical zipper fly.



The jeans feature a classic five-pocket construction.
The inside of the coin pocket features a glimpse of the red selvedge edge, bringing out the character of the fabric even in this subtle, easily overlooked detail.



A cowhide leather patch is placed at the back.



A label on the inside indicates that the garment was produced at a partner factory of Japan Blue Co., Ltd.



Turn up the hems and the red selvedge edge appears along the side seam, adding a subtle touch of detail that reveals itself when the jeans are rolled.





The silhouette is semi-wide and tapered, with generous room through the hips and thighs.
What makes this taper distinctive is that it is not achieved solely through the pattern. The significant shrinkage that occurs when the minimally finished fabric is given a one-wash treatment creates the distinctive three-dimensional shape and silhouette.
