Why do wedding cars have ribbons?

En route to the event it is customary to put ribbons on the bonnet, usually in white or a light colour. The custom dates back to friends of the bride and groom decorating the wedding bed with flowers and ribbons. Well-wishers would escort the couple to their marital bed, “bedding” the newly-weds. It was said the crowd wouldn’t leave until the new husband and wife has stripped off and were in bed together, symbolising the importance of procreation. Luckily new couples don’t have an audience, but the decorating of the wedding car with ribbons is thought to stem from this ritual.
