The pattern of dormitory bed curtains depends on your favorite style. You can ask your roommate. If you have a good relationship, you can consider buying a series together. In terms of thickness, it also depends on the privacy you want to achieve. I bought it myself, which is thicker and relatively expensive. I have a friend who bought it cheaply, but it is so thin that I can't stop playing with my mobile phone at night. It's also transparent, but it's okay if you don't turn on the light in bed, so it depends on your actual situation. The lower berth is better than the upper berth. You don't need to buy a curtain top, but there will be a gap. If you like hiding, you can also buy a curtain top.
