Thanks to Marie Kondo even men like me are opting for minimalism and good organization. I have been looking to purchase a trench coat. However, I am that guy that frequents meetings, casual functions and loves the outdoors as well. Is there one coat in a dark color that can go well with both casual and formal wear? I wouldn?t want to stock up on so many coats that is why I am asking for a recommendation of a versatile one.
