To ensure your tie fits properly start with a shirt that fits well. Your shirt collar should be loose enough for comfort but snug enough to sit well. The perfect fit for a shirt collar will allow enough room to fit a finger between the collar and your neck. Your shirt collar should feel comfortable.
• Your tie should end about an inch above your belt buckle
• The tie knot should not force up the tips of your shirt collar
• The inverted triangle of the tie knot should fit neatly into the triangle created by your shirt collar.
