From Function to Fashion: Men’s Underwear Through the Ages
From Function to Fashion: Men’s Underwear Through the Ages
Underwear is something most men put on without much thought. Yet, throughout history, men’s underwear has evolved dramatically — in purpose, design, and meaning. From simple garments meant to protect and preserve modesty to today’s fashion-forward pieces that express identity and style, the story of men’s underwear mirrors broader changes in society, technology, and culture.
From Linen and Wool to Industrial Innovation
In medieval Europe, men typically wore loose linen drawers known as “braies,” often paired with a long undershirt that doubled as sleepwear. These early undergarments were primarily functional, providing a barrier between the body and rough outer fabrics while helping maintain cleanliness in an era when bathing was infrequent.
The Industrial Revolution of the 19th century transformed underwear production. Cotton became widely available, and new manufacturing techniques made undergarments more affordable and accessible. Men began wearing closer-fitting pieces, such as long underwear — or “long johns” — which offered warmth and hygiene. The rise of mass production also meant that underwear was no longer a luxury but a daily necessity for men across social classes.
The 20th Century: Comfort, Sport, and Masculinity
The early 1900s brought a shift toward practicality and comfort. During World War I, American soldiers were issued lightweight cotton undershirts and snug-fitting shorts, which many continued to wear after returning home. These military garments laid the foundation for the modern T-shirt and boxer brief.
By mid-century, underwear had entered the realm of commercial fashion. The introduction of elastic waistbands, synthetic fibers like nylon, and later spandex revolutionized fit and comfort. Advertising began to link underwear with ideals of masculinity and physical fitness. Iconic black-and-white images of men in crisp white briefs became cultural touchstones, signaling that underwear was no longer just about function — it was about confidence and identity.
The 1980s and 1990s: Branding and Boldness
In the 1980s, men’s underwear took center stage in fashion. American brands such as Calvin Klein turned it into a symbol of status and sex appeal. The visible waistband, emblazoned with a designer logo, became a fashion statement in itself. Underwear was no longer something to hide — it was something to show off.
The variety of styles also expanded. Briefs, boxers, and the emerging “trunk” cut each offered a different look and feel. Boxers suggested ease and freedom, while briefs conveyed athleticism and control. Choosing a style became a way for men to express personality and attitude, reflecting a growing cultural openness around male body image and self-expression.
The 21st Century: Sustainability and Self-Expression
Today, men’s underwear is more diverse than ever. Designers experiment with materials ranging from organic cotton and bamboo to high-tech fabrics that wick moisture and regulate temperature. Comfort remains key, but sustainability and ethical production have become equally important to many consumers.
At the same time, underwear has become part of a broader lifestyle aesthetic. Social media and influencer culture have made it acceptable — even aspirational — for men to care about fit, color, and brand. The line between underwear and outerwear continues to blur, with some styles designed to be seen rather than hidden.
