Soft silk cotton Aloha shirt. Slightly oversized, so it can also be worn as a light jacket. A standard build man, 165cm tall and 60kg, was wearing it. Since it contains silk, it has a smooth drape, and the sleeves fall straight down, creating a relaxed silhouette for a beautiful coordination. Because it's silk, you can hand wash it with detergent in water. Silk is said to be difficult to wash, but I think you can do it without worrying too much.
