Why do brides need something old, new, borrowed and blue? This question is linked to a British poem with guidance for what a woman should wear on her wedding day to have good luck. The poem goes like this: "Something old, something new, something borrowed, something blue, and a sixpence in her shoe."
    Like many old traditions, it is not easy to say exactly where this saying comes from. The Oxford Dictionary of Superstitions says the poem dates back to the nineteenth century. But the belief in the good luck of wearing blue is much older. Since ancient times, blue was thought to represent loyalty and purity in some cultures.
    Wedding websites offer different explanations for the meaning behind this poem. They suggest that wearing something old represents the bride’s link to her family and the past. Many women may choose to wear a piece of jewelry that belonged to a mother or grandmother.
    Wearing something new is said to bring good luck and success. For many brides, their wedding dress is the new object they wear.
    Wearing something borrowed is said to serve as a reminder that the bride can depend on the support of her family and friends. So she might borrow a piece of clothing or jewelry from a friend or family member.
    There are many choices for what to wear that is blue. We asked several married women what their "blue" item was for their wedding. One woman said she wore light blue shoes. Another said she wore a blue garter around her leg. One wedding planning website suggested that a modern bride could paint her toenails blue or get a blue tattoo.
    The Oxford Dictionary of Superstitions says a bride would wear "a silver sixpence in her shoe" to have wealth. But it says the silver could also protect the bride from evil coming from her former boyfriends. However, putting a silver sixpence inside a shoe is generally not a tradition followed by brides in the United States.
