Judge others by what they wear?

Heya!! XD
Do you guys judge other people by their clothes, shoes, branded items, hair etc...? I don't know, but I really don’t do this.
Someone who's wearing nice and branded clothes may be regarded as being rich... I'm sick of it. Well, it’s okay to make assumptions about people based on their clothing, but you can't say someone is rich/poor because of branded items they use.
Hh.. Most of my friends do that, especially their parents. They're just like... er, uneducated -_-
