History of National Wear Your Pajamas to Work Day

Originating in North America, the name and garment known as pajamas are now used all around the world (regions of which are now occupied by the U.S. and Canada especially). The influence of the British empire on the greater Western world and the rest of the world, in fact, contributed to the increasing popularity and use of pajamas. Before this, pajamas were known as “mogul’s breeches” and were first worn in England as “lounging clothing” in the 17th century. However, these lounging clothes eventually disappeared. The term ‘pajama’ was first used in English in the 19th century. Pajamas didn’t become fashionable in Britain or the rest of the world until 1870.Traditional pajamas, which were made up of a shirt and pants, are where modern pajamas got their start. Pajamas have evolved to the point where they now come in a variety of styles and designs, some of which use unusual or non-traditional materials. Pajama bottoms are frequently purchased separately because both men and women like to sleep or lounge in just their pajamas, sometimes paired with a t-shirt.Even though they differ from other sleeping apparel, such as nightgowns, pajamas can occasionally be found with other types of nightwear. For instance, wearing a shorter nightshirt as a top. For the wearer’s convenience in using the restroom, certain pajamas are designed with a butt flap, also referred to as a “trap door” or more popularly as a “drop seat,” which is a buttoned aperture in the seat.
