i dont think the clothes that you wear tells you about how the the person is and whats he like. Maybe he/she just cant afford any clothes or maybe they just really dont care about fashion and all this stereotypes stuff, on how you have to have all this branded clothing and have everything what the celebs have.
it just really depends to a person if shes wearing a very revealing clothing then some people may assume that she's a H but u really cant judge them but u cant blame the people that sees them, their wearing a hs uniform.
