The Trousers
Interpreters mentioned that buying trousers from someone other than their owner might indicate marrying a woman without a guardian. New trousers suggest a virgin woman, and wearing trousers in general may symbolize chastity and the well-being of the wife and family. It was also said that wearing them inside out might indicate committing an indecency by family members, and they could signify travel or the good state of the household.
