Put on a yellow, brown, or green tie to go with the suit. Heath Ledger’s character wore a yellow and black tie with a geometric pattern on it. When in doubt, a simple brown or green tie will work with basically any version of the outfit. Choose a tie that goes well with the suit jacket to keep the outfit cohesive. You can tighten the tie all the way for a more formal look, or loosen it up a little to go for a more unstable vibe.
