If it is the former, as long as it is big, don't care too much about other colors.
If you go shopping in class, it doesn't have to be big. The default topic is girls. I think the color of main clothes depends on the color of clothes. Generally, black and white solid colors can't go wrong, and it's easy to wear clothes. Of course, light colors are fine. My classmate bought a light blue one, which looks good on the back.
