This is a thermal cut-and-sew top from Kelen with a mock neck design. I purchased it a few years ago and wore it several times, washed it, and then stored it at home. I am selling it because the size no longer fits. Although it's thermal fabric, it has a relaxed silhouette and is stretchy, making it comfortable to wear. It has a simple design, but the mock neck, the shoulder and arm paneling, and the raw edges on the sleeves and hem provide accents. Made in Japan Size 40 99% cotton, 1% polyethylene Shoulder width: approx. 61.5 cm Body width: approx. 62 cm Sleeve length: approx. 50.5 cm Length: approx. 73 cm *Please note that these are amateur measurements, so there may be some errors.
