Thick rope-like strands woven into big weight and even bigger texture fabric pays homage to a historically significant sewing technique. This is the Indigo Monster Sashiko Workshirt. 
The inspiration for this style is the traditional Sashiko sewing technique. Used as a functional sewing technique for repairs and decorative effects Sashiko is respected for its handmade style, prominent stitching and patterning effects. This style uses a Dobby weave to recreate the prominent stitch and geometric lines and then dials up the texture to absolutely beautiful levels. Imagine the plushest cotton rope interlaced together to create a hand woven look, huge texture and flowing feel. That's what we have here. Even better is the rugged 12 ounce weight, giving this style true vintage appeal. The double indigo color is the perfect finishing touch. Meet one of your most special workshirts.
This beautiful indigo fabric starts out a dark inky blue and ages beautifully like a pair of raw denim. Indigo can be darker in person. Dye bleed is expected with this piece.
Several construction details define our workshirt. The first is ample triple needlework with a classic chain stitch runoff. Triple needle is a specialized stitch not found on standard button downs and that serves as the heart of any good work shirt. Ours gets triple-needle flat-felled yoke and side seams with chain stitched bottoms. We also allow the side seam chain stitch to “run off” the end giving you three chain stitch ends on each side. We bar tack to ensure the runoff can’t compromise the security of the side seam. The second detail is double chest pockets. We keep ours a bit cleaner, without flaps, but use button closures and double bar tacks in each corner for added strength. The left chest pocket gets the addition of a small pen slot. The third detail is the side hem gussets. It’s a small functional element and looks absolutely great. On our selvedge styles, we incorporate the selvedge on the bottom. Finally, we love the chin strap. Ours is small enough to be tasteful while still reminding you of the workwear roots of the garment. We created new custom Corozo buttons specifically for our work shirts. Overall, this is one of our most intricately constructed garments and one of the most costly to produce.
Our workshirts will be available in our Classic and Slim fits. The main differences in details between our workshirts and our other shirting come down to construction - no back box pleat, and differently shaped side scoops. The Slim fit has a more tailored body as compared to our Classic fit. Chest and waist come in to provide a more fitted option. Details are in our fit guide now.
