Stick to a black tuxedo, a white shirt, and a black bow tie. A tuxedo with tails is required for full evening attire. If the wedding is not black-tie, you can wear a suit that is not black. To avoid popping out, stick to basic dark tones. Wedding guests are frequently advised not to wear white. However, there are many successful weddings where whites are worn without appearing too dressy. If you are having an outdoor wedding, consider wearing a jacket or cardigan for added comfort on what could be a hot day. In colder climates, it might be appropriate to bring a coat or wrap for guest who are planning to stay after the ceremony for pictures or dinner. Black and white wedding themes work because they're understated and elegant. Don't go for excessive color or design; keep it simple and clean. The most important thing to remember when attending a black-tie wedding is to respect the tradition and arrive dressed appropriately. Even if you are only going as a guest, you should still show up in a tuxedo or long gown. It shows that you take your wedding ceremonies seriously and make an effort to look good.
