Tradition and custom, the twin foundations of etiquette, influence almost every aspect of a wedding. Wedding expert Antonia Swinson tells you everything you need to know on the subject in Wedding Etiquette.

The bride's bouquet: There's no rule to say that the bride must carry a bouquet, but most do, since flowers add a decorative touch and give the nervous bride something to do with her hands. Traditionally, the bride throws her bouquet as she leaves the reception. Whoever catches it will supposedly be the next to marry.

The reception: The bride and groom arrive first, then the bridesmaids, best man and parents. A receiving line lets you welcome your guests and gives them the chance to congratulate you. The usual order is: bride's mother and father, groom's mother and father, bride, groom, chief bridesmaid and best man. If you don't want a formal receiving line, you and your families, or just you and your groom, could stand in a group to welcome people.

Speeches: Speeches are an important opportunity to voice the thoughts and emotions particular to the day, and wedding guests make a receptive audience. The normal order of speeches is: the bride's father (or whoever gave her away), the groom; followed by the best man. Sometimes the bride and/or chief bridesmaid will speak. They can be slotted in wherever seems appropriate, but make sure the toasts are still made and answered.
