Hello, it's not appropriate for college students to wear a halter top with shoulders for girls in class. There are a lot of other free time in the university, and you can wear whatever you want. But in the classroom, it is not good to wear suspenders and shoulder-length clothes, and students will be a little exposed in the classroom, which will damage the image of female college students. Besides, school is not a society. Both schools and teachers believe that what they prefer to see is that they want students to concentrate on their studies. If they wear halter skirts and halter tops, going to class together may also leave a bad impression on the teacher. But you can try adding a small coat to the skirt. Actually, it depends on you. There are not so many rigid requirements for dress in universities. It's just that many people think it's not good to wear sexy girls at school, but it's actually good to wear clothes by yourself, if you can care about other people's attitudes and opinions. The above is my opinion on the problem that college girls wear suspenders in class, which is not suitable for their shoulders. I hope it can be adopted.
