History behind the term 'Underwear'


The Beginnings

During the 1300s, the term 'underwear' had not yet come into existence. Instead, people referred to these undergarments as 'drawers' or 'breaches'. These early undergarments were made from linen and were typically worn by both men and women to serve as a protective layer between their bodies and the outer garments. They were loose-fitting and often tied at the waist with a drawstring.


Transition to Cotton

In the 1600s, the fabric used for underwear began to transition from linen to cotton. Cotton became increasingly popular due to its comfort and affordability. The loose-fitting drawers were now called 'shirts' and 'shifts'. These undergarments were still mainly practical rather than fashionable in nature.


Evolution of Styles

During the 1800s, fashion began to influence the design and style of underwear. Corsets became popular for women, reshaping their figures and emphasizing the hourglass silhouette. As a result, the term 'corset cover' was adopted to refer to the undergarment worn on top of the corset to protect it from sweat and body oils. Men's underwear, on the other hand, began to evolve with the invention of the union suit, a one-piece undergarment combining a shirt and drawers.


Rise of Modern Underwear

As the 1900s dawned, significant advancements were made in underwear design. Elastic waistbands were introduced, providing a more secure fit and greater comfort. With the rise of cinema and Hollywood's influence on fashion, underwear began to be marketed as a symbol of sensuality and allure. Lingerie, a term derived from the French word 'linge' meaning 'linen', emerged to describe women's elegant and provocative undergarments. This era also witnessed the introduction of briefs for men, revolutionizing their underwear choices.


Continued Evolution

In the present day, the term 'underwear' encompasses a wide range of undergarments for both men and women. From classic boxers and briefs to thongs, bras, and shapewear, there are countless options available to suit individual preferences and styles. Underwear has become not only a functional necessity but also a fashion statement, with various materials, colors, and designs catering to diverse tastes. The cultural significance of underwear continues to evolve, reflecting changing societal norms and attitudes towards body image and self-expression.
