As to what to wear, most wedding invitations clearly state what the dress code will be. Expect it to fall between black tie and business casual, although 95% of the time if you show up in a dark suit, white shirt, and muted tie with proper dress shoes you’ll be perfectly dressed. If the invitation does not cover what guests should wear, there are a number of clues you can pay attention to that will help you figure out the expected attire:
- First, take into account the location; an outdoor wedding in rural Wisconsin is going to be by its very nature less formal than a wedding at St. Patrick’s Cathedral in New York City.
- Second, the time of day; day weddings are often less formal than evening ceremonies. In fact, the wearing of a tuxedo before 5PM is considered a faux pas by many traditionalists, although in the US this rule is often ignored.
- Third, examine the invitation itself. If it looks like they’ve spent a fortune on the invites, you might want to spend a little time dressing the part of a considerate guest.
