Here are some “old wives tales” and old customs and traditions:
A bride is lucky if she wears old shoes.
If a cat sneezes on the day before a wedding, the bride will be lucky in her marriage.
A young bride would wear her hair long and loose as a symbol of her youth and innocence.
It was OK for a woman to propose to a man during a leap year.
If the groom drops the ring during the ceremony, the marriage is doomed (may be that is why today we have the ring-bearer?)
If you see a rainbow on your wedding day, it is a good sign.
If you see a black cat on your wedding day, it is a good sign.
Pretty much if you see anything on your wedding day it is a good sign!
