Wearing pearls: this is one of those wedding myths with both bad luck and good luck meanings. The ominous version of this myth holds that pearls represent future tears; thus wearing them will bring many tears and heartache in the marriage. The luckier version of this implies that the pearls take the place of the bride's real tears, thus she'll have a happy, tear-free wedding.
Tears on the wedding day: it is considered good luck for the bride to cry during her wedding. She will have cried all her tears away leaving none for the marriage. Another theory holds that a bride's tears are good luck as they bring rain for the crops.
Rain on the wedding day: this is another good luck - bad luck wedding myth. In the good luck version, rain is said to foretell the coming of children just as rain promotes growth in the farmer's fields. In the unlucky version, rain drops represent the many tears a bride will cry throughout her marriage.
