What is the origin of pajamas?

Pajamas originated from the Persian Word "pāy-jāmeh," meaning "leg clothing," and were introduced to the Western world through British colonial influence in India during the 19th century. Initially worn by men, they consisted of loose-fitting trousers and a matching shirt. Over time, pajamas evolved into the comfortable sleepwear we know today, becoming popular for both men and women in various styles and fabrics.
