"Something old" is the first line of a traditional rhyme which details what a bride should wear at her wedding for good luck:
and a silver sixpence in her shoe.
It is often recited as the four "somethings", not including the sixpence. The rhyme appears to originate in England, an 1898 compilation of English folklore reciting 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.
