Materials

Made with 20-count thread for a moderate thickness that balances toughness and softness.

White weft threads are combined with indigo warp threads, creating subtle shifts in color depending on the light, expressing a rich, layered blue.

Offers both durability and comfort, with a texture full of character.

Fabric
Achieves a perfect balance between dressy and casual styles—an appeal that other fabrics can’t replicate.

Enjoy the Aging Process
The greatest charm of indigo chambray lies in its patina over time.
Indigo plus sulfur dyeing on the warp threads gradually changes in tone with repeated wear and washing.

The more you wear it, the softer it becomes, and the deep blue develops a unique character that reflects your personal style.

About Indigo Dyeing and Sulfur Dyeing
Indigo dyeing: Uses natural or synthetic indigo to color only the surface of the fibers. With wear and washing, the color gradually fades, revealing a distinctive texture and look.

Sulfur dyeing: A method known for durability and resistance to fading. It produces a subdued hue, and when combined with indigo dyeing, creates a deep, layered blue.

From Workwear to Dress Shirt
Chambray was originally a staple fabric for work shirts.

Preserving its practicality and toughness, Kamakura Shirts refined it into dress form by carefully designing the collar shape, tailoring, and silhouette.

The result is a shirt with understated elegance—not too casual—that works for both casual and business settings, making it a new staple for adults.

Styling
Business Style: Pair with a navy jacket and silk tie for a traditional yet polished impression. The collar and silhouette complement tailored jackets, creating a professional look without stiffness.

Business-Casual Style: Wear with a sport coat and trousers, no tie, for a balance of relaxation and refinement. The shirt’s three-dimensional shape and fabric texture create effortless sophistication.

Casual Style: Combine with denim or chinos to highlight the fabric’s rugged charm for off-duty days. The shirt’s fading and shadows add depth to your outfits.

Versatile enough for both on- and off-duty wear, this is a wardrobe essential.

What “SPORT” Means
This shirt is Kamakura Shirts’ reinterpretation of the button-down shirt—the iconic piece of 1960s American Ivy style that once took the world by storm.

Its hybrid design combines nostalgia with freshness: a soft, long-point collar with specially designed interlining, a slightly wider placket, and slightly shorter cuff height.

The narrowed yoke creates an elegant back view.

In the U.S., more casual button-down shirts are called “SPORT SHIRTS,” which is where the name comes from.
