Sounds like you found out just in time MTRSpeed that the worth of an entire person can be instantly and accurately judged by the labels on his attire. Inntelect and compasion are only important to the poor.

Seriously though most people do judge you by what you wear ,grooming etc and to a certain extent you can profile someone fairly well by how they choose to present yourself. Ideally what you want to do is dress so someone who is quite good at reading people in this way will think what you want him to think.

It is not about spending a lot of money but spending it in the right places.
Considering I generally wear a pair of canadian army issue sweatpants a casio G-shock and an old Hoodie means it is not important to me what others think.
When I want I am good at making a first impression. The right gear and confidence
even if you are scared wittless fake confidence will work fine.
