and a sixpence in her shoe.
The old item provided protection for the baby to come. The item borrowed from another happy bride provided good luck. The colour blue was a sign of fidelity. The sixpence—a silver British coin—was a symbol of prosperity or acted as a ward against evil done by frustrated suitors. An 1898 compilation of English folklore recounted that:
In this country an old couplet directs that the bride shall wear:—"Something old, something new, Something borrowed, something blue." "The something blue" takes, I am given to understand, usually the form of a garter, an article of dress which plays an important part in some wedding rites, as, for instance, in the old custom of plucking off the garter of the bride. "The something old" and "something blue" are devices to baffle the Evil Eye. The usual effect on the bride of the Evil Eye is to render her barren, and this is obviated by wearing "something borrowed", which should properly be the undergarment of some woman who has been blessed with children: the clothes communicate fertility to the bride.
The earliest recorded version of the first two lines is in 1871 in the short story, “Marriage Superstitions, and the Miseries of a Bride Elect” in St James’ Magazine, when the female narrator states, “On the wedding day I must ‘wear something new, something borrowed, something blue.'”
The first recorded version of the rhyme as we now know it (the so-called Lancashire version) was in a 1876 newspaper, which reported a wedding where the bride “wore, according to ancient custom, something old and something new, something borrowed and blue.”
Another compilation of the era frames this poem as "a Lancashire version", as contrast against a Leicestershire recitation that "a bride on her wedding day should wear—'Something new, Something blue, Something borrowed'...", and so omits the "something old". The authors note that this counters other regional folklore warning against the wearing of blue on the wedding day, but relates the use of the color to phrases like "true blue" which make positive associations with the color.
The final line "and a sixpence in her shoe" is a later Victorian addition. By 1905, the full rhyme had crossed the Atlantic to the USA and appeared in the novel Purple and Fine Linen by Emily Post. 
At the wedding of Prince William and Catherine Middleton, the bride had:
- something old – Carrickmacross lace
- something new – a pair of diamond earrings made by jewellers Robinson Pelham and given by her parents
- something borrowed – a diamond tiara made by Cartier which had been bought for The Queen Mother, and which was subsequently given to The Queen on her 18th birthday
- something blue – a small ribbon sewn into the inside of the dress
