How do I know when to wear a tie with business casual clothes?
Perhaps the better question is, what’s best for this ensemble? Your goal is to find the right look for the outfit and occasion. A great tie that works with the fabrics, color scheme, and patterns you’ve chosen can instantly add flair to your look. Your well-chosen tie can add texture and color without changing the essential nature (casual or dressy) of your clothing.
If you’re concerned that a tie is needed for an occasion but want something beyond the conventional look of a long tie, consider a bow tie or a knit tie.
