How to dress for college students majoring in civil engineering (bridge) on campus?

It should be said that all formal occasions should be dressed formally, and so should civil engineering majors. If you want to make a good impression on the interviewer and stand out from the candidates, you'd better dress neatly. A suit is a good choice. As for the price, don't be too expensive, so as not to leave a flashy impression on the cotton tester. 300 to 500 is fine.
