This highly popular set-up item is an open-collar shirt made from fabric featuring the brand's original autumn leaf pattern, printed using inkjet technology. It utilizes a thin, ripple fabric, often used in summer clothing like jinbei and yukata, known for its airy texture and resistance to clinging to the skin due to its uneven surface, providing excellent breathability. The entire back yoke features gathers, creating a slightly puffed silhouette, and it has short side slits with a difference in height between the front and back, resulting in a boxy silhouette. A patch pocket matching the body's pattern is located on the left chest, with the logo embroidered on it. The buttons are original buttons with the logo engraved.
