The rules for what male guests should wear to the wedding are quite precise. According to the royal wedding invitation, men are required to wear one of three kinds of dress Friday: a military uniform, a morning coat or a lounge suit.
A lounge suit isn't exactly as casual as it may sound; it means a coat and tie. As for the morning coat, it's a coat with the front cut away-so that just the back part hangs down in the back. The coats come from the days when men rode horses and wore top hats.
Not Just About the Suit and Dress
But royal wedding attire isn't just about the proper suit or dress; it's also about the accessories. Dents Gloves, for instance, are synonymous with fine handwear in Britain and are a staple of the royal family.
For three centuries, the gloves -- lovingly hand-stitched at a factory in Wiltshire -- have been worn by kings, queens and attendees of royal weddings.
