Something old, something new, something borrowed, something blue, and a silver sixpence in your shoe - the less known final line of the rhyme, slightly uncomfortable but symbolised happiness and spiritual and financial wealth.
The bride wears something old as a symbol of her old life that she is leaving behind. Something new refers to the new hope in her new life. A borrowed item (usually a garter) from a happily married woman is believed to pass on good luck to the newlyweds. Blue symbolises purity, faithfulness and her commitment to her new husband.
