This is a navy, jersey-material stretch jacket from United Arrows. It's versatile for business casual, travel, golf, and more, suitable for various occasions (spring, summer, autumn, and winter with a sweater underneath). It's also made of a material that can be washed at home. Regarding the color, the last three photos are believed to be the closest to the actual item. The condition is good, and I believe you can use it for a long time. The size details are as follows, and it fits me perfectly at 175cm and 65kg. Please note that the following measurements are approximate due to amateur measurements. Length: 69cm Shoulder width: 45cm Chest: 100cm Waist: 92cm Sleeve length: 59cm
