Lookism is when people judge or discriminate against someone based on how they look. This might happen in all areas of life, like when you go to a job interview or when someone talks to you on the street. Some people might think that people who are attractive are better than people who are not as attractive or they might think that people who are skinny are better than people who are bigger. This kind of thinking is wrong and everyone should be treated and respected the same no matter how they look.
