Many college students rarely think about what to wear to class. Instead, they are known for wearing comfortable clothes to class. This is because they woke up at the last minute and they also want to be comfortable. Often students will wear shorts and a t-shirt or jeans and a sweater if they are cold-natured.
As long as the clothes fit well and look good, then that would make them look cool. It is more important for the clothes to fit well and accentuate your assets and diminish your flaws. However, these clothes also should be comfortable or the students will most likely not wear it again. If not, they will most likely not wear them since they are not comfortable.
