In medieval times a
queen was expected to travel with a large entourage and make a grand entrance that would 'wow' all guests. Therefore the
queen was alloted an extra hour to prepare for all public events without being considered
late. This "grace period" became known as the queens hour and was often spent discussing the queen and predicting her entrance attire. Now used in some circles to indicate when
one won't be on time, but it will be worth it for the fabulous-ness of dress or personality of the late comer.
