Answer:
Sumptuary laws
Explanation:
Sumptuary laws are laws designed to prevent a specific group of people from buying a specific type of goods: usually luxury goods.
After the deadly bubonic plague of 1348 to 1352, also known as the black plague, or the black death, peasants had more land available either for themselves, or to work as laborers, and their wages rose because of that. They could now afford some small luxuries like higher quality clothes.
This angered the nobility, who decided to pass sumptuary laws to prevent the peasants from buying certain type of goods.
This laws wer also passed in the cities, where the rich merchants and artisans were acquiring goods that the nobles thought should only be for them.
