First of all, I don't know what position you are interviewing for, so I still mind you wearing a formal suit. You'd better wear a suit, a traditional suit. But remember, if you wear dark leather shoes, you must wear black socks, which are very delicate. Hair should be simple, neat and clean, not sloppy. Don't put on any styling cream, so even flies can't stand. The suit should be stiff, and it's safer to take it to the dry cleaner for cleaning and ironing. If the job you are interviewing for is the position of manager in charge, that is, the shirt and tie inside, you should not exaggerate the color, which will make you very conspicuous. If not, you can wear some leisure suit without tie, some colored shirts and unbutton a button. That will make you look fashionable and energetic. In fact, the interview dress of boys is not as important as that of girls. Just remember to be clean and tidy, and the other is the most important strength. Come on! I hope your interview is successful.
