I wear a lot of different things, from casual to less casual and I've always noticed that people treat you differently when you wear different clothes. I guess I kind of act differently too depending on what I'm wearing. Like if I'm wearing something more sophisticated I'll look smarter. Do you think that's true?
If I see a guy with his pants hanging down his ass and a huge shirt with beer or some rapper giving the middle finger on it I'm going to see him as a completely different person than if he wore a nice pair of pants, or jeans and a appropriate shirt.
I have no problem judging people based on how they dress- you spent money on those clothes, you chose to wear them, that's how you want to be seen. It doesn't take much effort to look respectable and decent.
There's a reason you dress up for a date or an interview, because people judge you based on what you wear.
In essence, clothes are symbols imbued with meaning. And the meaning of a symbol is determined by many things (i.e. culture, the fashion industry, color psychology, etc.).
And yes, sometimes clothes can make a person behave differently too. When I wear a graphic tee along with straight jeans and sneakers, I act more laid back. But when I wear a tailored blazer, tailored dark denim, and polished ankle boots, I act more classy.

Yet people still do. Underneath all the layers is a human being. Sometimes people forget that.
