Where did the "something blue" come from?

Here's the most common explanation:

The rhyme dates back to the time of Queen Victoria and is often quoted "Something old, something new, something borrowed, something blue, and a silver sixpence in her shoe."

Something old: Represents continuity with the bride's family and the past, usually a ring or a piece of jewellery that has been passed down through the family from generation to generation.

Something new: The wearing of something new shows the bride is looking to the future of her marriage. This could be the wedding dress or the lingerie worn under the dress.

Something borrowed: a token borrowed from a happily married friend or relative in the hope that some of their happiness and good luck will be transferred to the new couple. A piece of jewellery is usually borrowed for the big day.

Something blue: The colour blue is believed to come from the Virgin Mary, who is often portrayed in a blue robe, blue is a symbol of purity, most often the something blue is the garter the bride wears.

A silver sixpence in her shoe: A Scottish tradition that actually started with the bridegroom putting a sixpence in his shoe to represent financial security and future wealth. The custom these days though is for the bride to have the sixpence in her shoe.

In general, not necessarily weddings.
