Wool, high-quality Chester coat purchased at United Arrows Harajuku Main Store. It has a superb sense of luxury. It can be used for both business and casual occasions. Of course, it can be worn beautifully over a suit. The size is 44. It's charcoal gray, and looks great with suits of any color: navy, gray, black, or brown. I wore it when I was 170cm tall and of average build, but I'm sadly letting it go because my size changed after I started weight training. The condition is very good, having been worn only twice.
