First when it comes to your belt make sure it matches your shoes. A Black Belt should be worn with Black shoes and a Brown Belt with Brown shoes. Second match your Socks to your pants. It is okay if it is not the exact same color but try and be very close. Remember never wear white socks with your outfit unless you are wearing sneakers. Third and one of the most important tips is make sure your Necktie reaches your belt. Anything too short or too long makes you look like an oaf.
