Step 1. Find Your Color
Whatever color you pick for your shirt, find a tie that has that same color somewhere in its pattern. A tonal match is very easy on the eyes, and immediately brings your shirt and tie together.
Step 2. Properly Proportioned Patterns
Just remember: big pattern, little pattern. You always want to easily discern between the size of your patterns. For example, if your shirt is gingham, pair it with a boarding-stripe tie. Or if your shirt is a shadow stripe, consider a tie with a paisley or dot pattern.
See how easy it is? Simply keep your colors coordinated and proportions on point, and you can do no wrong.
