I believe the color scheme of a man’s outfit is often the very first thing people notice, and after that, the details come into play. As you mentioned, the coordination of belts with shoes is quite crucial, and this applies to the watch in case its strap is leather as well. What fascinates me is that most of these subtle details are identified subconsciously rather than being observed on a conscious basis. Take shoes, for example: they’re one of the most decisive factors in forming a first impression, yet most people don’t consciously observe or think about them. Instead, the impact happens on a deeper level that is felt at the very first perception. For me, the most interesting ‘signature detail’ is how the patterns or even plain colors of a tie, pocket square, and shirt can complement each other to create harmony in a dressing style 😇
