Hello, dongjoon, Thanks for sharing your observation, I liked how your describe your economics professor because economics is my department, I have had some professors are looks like the one you have wrote about, they wear clean clothes, usually shirt with jeans or shirt with suit pant. Like you said, their appearance “tells that he is a very conservative”. I think this may because they are sanding in school and being the role of professor. Being conservative is a way of being responsible to students and their career. however, I am not sure about your words:”he follows a value that schools or parents taught”. Do you mean they got high level education and being a professor is flowing the values that schools and parents told him ? I cannot compeletely agree with you, A person’s clothing and behavior in his working environment cannot tell his value of his life. Your third example is a business girl, “Her well designed clothes and perfectly fit into her body indicated that she has a strong confidence on her jobs and has a full of knowledge on her job” is a great observation.
