However, based on the need for survival, humans have appreciated that raw simple undergarments are made from hides, leaves, and the like. In a broad sense, the garment to be worn between the body and the outer garment may be called an undergarment. The clothing industry has developed a variety of patterns for Underwear, including bustier, brassiere, waistline, chest-attached tights, vest-style shirts, short waists, etc., known as underwears from the clothing community in 1983. The bra, girdle, and even trousers, pantyhose, which only cover the shame, and the outer wear vest or seamless underwear, which have evolved from the bustier since the nineteenth century, are all incorporated into the rows and columns of the undergarment.
