Definitely not. No one should be judged on their clothing. However, people do that all the time. If you go to a job interview, the interviewer will judge their candidates based on what they wear. The same can be said for younger people – teenagers or even young adults. They may judge people because they expect them to wear brand name clothing to work or school.
Some people do not put an emphasis on clothing and want to look presentable, but they don’t want to spend a huge amount of money on clothing. They may be spending their money on something that they deem is important. Therefore, the person who is doing the judging would not want to be judged based on something they don’t think is important.
