Size: S Width: 53cm Length: 74cm Shoulder width: 44cm Sleeve length: 62cm This shirt was inspired by vintage band collar shirts, likely from the British military. The original length, which exceeded 80cm, has been modified by WORKERS to about 76cm. This "Modified" length, as WORKERS calls it, allows the shirt to be worn either tucked in or out. The elbow width is made more generous. To prevent the shirt from pulling when you move, not only the body width but also this "sleeve width" is important. The front has a rounded, overlapping construction. This feature is said to be from old shirts that "were used as underwear" (though that's a bit unsanitary...). Nowadays, it gives a classic feel. Material: About 3-ounce poplin. This shirt fabric has a smooth feel. There are tucks on the back, left and right, so it won't pull when you reach your arms forward. The resin buttons won't crack in the wash, so you can wash it without worry every day. This is a "practical" shirt with a stylish design.
