For me, one's mode of dressing is a reflection of one's perspective of oneself. The attention and level of keeness shows how much self-awareness one has for themselves. And although the level of attention may vary from person to person, a good amount of attention is necessary in presenting oneself well.
And just like the popular saying, you may want to dress well if you'd like to be treated well. It extends to how one smells too. I love when people smell nice; I think it adds to fashion too.
I just learned something new from you; enclothed cognition. Now I know how it is that my dressing affects my drive for certain ocassions.
Your fashion style in these photos show that you know that you know what you are talking about. You look sharp always.
