"Blue" has been connected to weddings for centuries. In ancient Rome, brides wore blue to symbolize love, modesty, and fidelity. Christianity has long dressed the Virgin Mary in blue, so purity was associated with the color. Before the late 19th century, blue was a popular color for wedding gowns, as evidenced in proverbs like, "Marry in blue, lover be true."
And finally, a silver sixpence in the bride's shoe represents wealth and financial security. It may date back to a Scottish custom of a groom putting a silver coin under his foot for good luck. For optimum fortune, the sixpence should be in the left shoe. These days, a dime or a copper penny is sometimes substituted, and many companies sell keepsake sixpences for weddings.
