While people don't usually like to associate people's dress style or such with who they are inside, I feel like it does bleed over in a sense.

Take me for example, since I think my fashion sense reflects aspects of who I am. Like the avatar I've drawn shows, my hair is actually incredibly messy (I've got a lot less hair in real life because I'm pretty bald due to genetics, but that's not the point) and I make no effort to groom it; in fact, I prefer it messy. That hints at a sense of unruly nature, which is very inherent in my personality since I refuse to be bound to any terms other than my own. It also implies I don't care about my public appearance and have no concern with formalities, and that I care more about my project than I do about looking presentable. These are all true assessments of me, and can be analysed by looking at me.

I don't believe physical appearance is all that matters, but how we choose to present ourselves does give hints about who we are inside.
