Something old, something new....
The original rhyme goes: Something old, something new, something borrowed, something blue and a silver sixpence in your shoe.
Something old represented a link with the bride's family and her old life.
Something new represented success and good luck in her new life.
Something borrowed, preferably from a happily married woman, was supposed to bring the same good luck and happiness to the bride
Something blue stems from the times when the colour blue represented purity and fidelity.
The silver sixpence in the bride's shoe was to ensure health, happiness and prosperity for the new wife.
I don't know if I will specifically do any of these on the wedding day. The 'something new' won't be so difficult, but not sure about the rest!
