Get a great one that fits with your personality and profession. It may take years to find the right tailor, or store to get your suits from. Finding the right hair salon and person to cut it right, may take some time as well but it will be worth it in the end. Natural looking hair is always better than gelled. Use little wax or other hairstyling products. Washing the hair on a regular basis should avoid dead skin cells dropping on your shoulders and make your suit look bad.
