The Evolution of Underwear: A Journey Through History
Underwear is a piece of fabric that we call loincloth in Turkish, which is used to mean “loincloth” in English, which is tied to the waist in ancient times. These diaper-like loincloths are the simplest form of underwear. It has been seen that it is used as both underwear and outerwear in hot climates. It is thought to be the only underwear of the Egyptian civilization, as seen in the ancient Egyptian paintings, especially in ancient civilizations.

The type of Pesh Tamal used among Indians is called “kowpeenam”. These loincloths still have a rectangular pattern, but their front and back views are in the form of thong panties. Peshtemals were diversified in Ancient Rome and were called subligaculum. It is seen that piece resembling shorts wrapped around the lower part of the body is worn by both men and women. Fragments of skin subligaculum were found during excavations of the Roman period.

Underwear has been used to reshape different parts of the human body in certain periods of the historical process. Additionally, because of the use of aesthetic appearance in these periods, extremely useless and unhealthy underwear emerged; In the upper body, corsets were used to slim the waist, and petticoats were used to shape the lower body.

Underwear made of pure wool is called “Sanitary Underwear”. The reason for the start of this movement is the use of dangerous dyestuffs containing “aniline” in fabric dyeing. These dyestuffs have caused health problems and poisoning on the skin which seriously harms the vagina.
The Romantic Era’s Influence on 19th-Century Underwear Fashion
With the rise of the Romantic movement in the 1890s, a greater emphasis on beauty emerged in both underwear and outerwear. During this time, the “S-Twist” silhouette became fashionable, with women wearing corsets to achieve this distinct shape. The petticoat was also a popular undergarment in the 19th century, contributing to the era’s idealized feminine image. With the awakening of the idea of sexual attraction at the beginning of the 20th century, a very different trend was entered in underwear. Wool laundry, which was fashionable in the 19th century and preferred because it was healthy, lost its popularity. Later, fabrics such as silk, crepe rosin, satin and georgette, which gave a sexy image, were started to be used.

The luxury and elegance that comes from the French word “linge”, which is called “lingerie”, has been popular for several reasons. It has been observed that these fabrics are much lighter than woolen clothes, more suitable for decoration with lace and embroidery, and are attractive.
At the end of the 1920s, Kestos Company in America developed a new model by attaching two triangular fabrics with elastic bands, crossing them on the back and tying them in the front. In addition, in the 1920s and 1930s, corset companies entered the bra business and made bras with underwire and in different cup sizes. With the discovery of synthetic fibers, as in all knitted products, it has been the beginning of a new era in terms of underwear and swimwear production. In 1935, Warner Bros. Co. introduced a sizing system for the “cup” region of the bar. In LATE 1940s, the use of extra sponges allowed the bras to be given different shapes. In 1948, frilly bras were produced by keeping the distance between the chest wide. Strapless bras were also made in the 1950s to be used with strapless dresses. In these years, bras were produced for the first time for adolescent girls and bustier was also used in these years.
