One sure way to prevent this problem is to avoid wearing a tie altogether. But in some occupations, wearing a tie is standard
attire. If you must wear a tie:
Buy shirts with plenty of neck room.
Leave your shirt collar unbuttoned beneath your tie.
Don't knot your tie so tightly that you can't slip a finger between the shirt collar and your neck.
If feasible, loosen or remove your necktie from time to time throughout the day.
