Samurai Jeans SOS26-ARS Indigo Sashiko Lattice Open Collar Shirt

The Samurai Jeans SOS26-ARS is a short-sleeve open-collar shirt built around one of the brand's most distinctive fabrics: an original indigo sashiko lattice cloth, woven and dyed entirely in-house. The result is a shirt that reads equally at home as a modern take on the classic aloha silhouette or as a workwear-inspired summer piece, easy to wear across all warm-weather styling.

The fabric's lattice pattern is reproduced through a combination of natural indigo and synthetic indigo blended dye, creating a deep, slightly purple tone that gives the cloth its unmistakable visual depth. Using a traditional Kasezome hand-dyeing process, the yarn is dyed in hank form before weaving — allowing uneven dye penetration and the kind of tonal variation that rope-dyeing simply cannot produce. Rather than fading out with wear, the resulting blue deepens and becomes richer over time, developing a character particular to each garment.

Cut into a relaxed silhouette with generous room through the body and sleeves, the shirt is finished with clean, simple detailing — an open camp collar, a single chest pocket, and urea buttons at the front placket. Refined enough to layer under an overshirt or wear open over a T-shirt, minimal enough to let the fabric's character take center stage.

Fit Notes: This shirt runs small. Compared to most global American brands, we recommend sizing up one from your usual size for the intended relaxed fit. As always, we strongly recommend checking our size chart and comparing it with your best-fitting shirt to find the perfect fit.
