There seems to have been a few instances in the 18th century of women dressing down, way down, for their wedding. It was said that if a woman went through the wedding ceremony naked, she would be forgiven of her debts. However, "naked" here means that she only wore a shift, smock, or chemise, which was something like a nightgown or undergarment. There are many newspaper accounts of such "naked marriages" throughout the 1700s in England and America. There is one instance of a bridegroom being forgiven of his debt if his bride removed her clothing at the ceremony.
Note that we have little information on how much money was forgiven, if any, by these weddings. Still, if the debt was small, it may have been worth a creditor's forgiveness just to see such a wedding. It did not always go off without a hitch. At one wedding in 1794, three male witnesses were required, so neighbors were recruited. One man was so flabbergasted at the sight of the bride that he was unable to swear his witness, and the debt forgiveness was thrown into doubt.
