Semi-formal attire for men is a dress code that is less formal than black tie or white tie, but more formal than business casual or casual. It is often described as being "dressy" or "smart" and is appropriate for a wide range of occasions, from weddings and parties to business events and formal dinners. The following are some key elements of semi-formal attire for men:

• A suit or sport coat
• Dress pants or slacks
• A dress shirt
• A tie
• Dress shoes

Semi-formal attire is slightly more relaxed than formal attire, but it is still important to dress in a sophisticated manner while showing personal touches in the ensemble. While there is room for expressing personal style through accessories and colorful touches, it is important to respect the occasion and not mistake "semi-formal" for "casual" or "relaxed". Some tips for accessorizing semi-formal attire include wearing a well-fitted suit or sport coat and dress pants, and adding finishing touches with accessories such as a pocket square or tie clip. Jeans are not considered formal enough for semi-formal events.
