An old Victorian rhyme says: Something old, something new, something borrowed, something blue and a penny in her shoe.
The saying refers to what a bride should wear or carry on her big day. The origin of "old" stems from either an old garter given to her by a happily married woman to convey happiness or symbolize the continuity of loyalty from the couple's friends. Something new is a symbol of luck and health in the future marriage. The borrowed item is supposed to give the bride's friends and family an opportunity to bestow upon her a good luck charm which must be returned for the luck to hold. Something blue originates from ancient Israel, when a blue ribbon was worn by the bride to symbolize her fidelity. The penny or any other coin ensures wealth for the future couple.
The veil is supposed to fend off evil spirits and the richly clad bridesmaids are there to surround the bride and to distract and confuse envious spirits or the devil from harming her. Today, practicality and professional commitments tend to determine the choice of the wedding day, but once it was of great importance which day of the week was chosen. Here is another rhyme:
Monday for wealth, Tuesday for health, Wednesday best of all, Thursday for losses, Friday for crosses, Saturday for no luck at all. Given that today statistically Saturdays are the busiest days for weddings, it either proves that there is not much truth in the saying or it doesn't bode too well for the institution of marriage.
