Every August 5th, we honor more than just a piece of clothing—National Underwear Day celebrates the layer that defines how you step into the world. Underwear is more than fabric against skin. It’s the partner in every moment you carry forward with purpose and presence.
The Origin
National Underwear Day began in 2003 as the brainchild of entrepreneur Michael Kleinmann, founder of Underwear Expert. With a background in digital media and a passion for changing how people think about their most personal garments, Kleinmann saw an opportunity to turn something overlooked into something celebrated.
At a time when underwear was treated as purely functional—and often ignored in fashion conversations—Kleinmann launched National Underwear Day with a bold statement in an equally bold location: New York City’s Times Square. The event featured models walking confidently in their underwear through the crowds, sparking conversation, media buzz, and a national dialogue about fit, comfort, and self-confidence. It was part stunt, part mission—and all heart.
For Kleinmann, this wasn’t just about marketing. It was about transforming underwear from an afterthought into a form of self-expression. He believed that everyone deserves to feel good in what they wear underneath—regardless of body type, gender, or style. National Underwear Day became his way of blending fun, fashion, and purpose into a celebration of individuality.
The Mission
This day isn’t about rules. It’s about reclaiming self-expression. We stand with all bodies, all aesthetics, and every morning ritual. Underwear isn’t basic—it’s your personal canvas. Our goal is simple: to elevate underwear from necessity to statement.
Why It Matters
Underwear touches more than just skin. It shapes your posture, your comfort, and even how you feel about yourself—before you greet the mirror. A well-chosen pair is softness that supports, structure that moves, and design that affirms. It’s about identity, function, and subtle pleasure—layered beneath everything.
How to Observe
Celebrate in a way that feels authentic. Maybe that means wearing your favorite trusted pair, adding mesh or bright cut to your rotation, or gifting someone who deserves better basics. Some share stories or selfies, while others trade quietly in confidence alone. Whatever you choose, honor the pair that fits your purpose—and consider supporting nonprofits that help others feel covered.
Why We Celebrate
Because the smallest layer often unleashes the biggest shift. Great underwear doesn't brag—it integrates. It sends a signal: that you’re comfortable with who you are, and ready for what’s ahead. National Underwear Day reminds us that when your foundation fits, everything else has room to rise.
Tips for Finding Your Fit
Great underwear fits like armor you forget you’re wearing. It breathes, it stretches, and it moves with you. Today is your permission slip to explore different styles—mesh, jock, brief, or wild print. If it brings ease to your day, it’s worth it. If it’s worn out, let it go. To care for yourself is to care for your base layer.
Parting Thought
Let’s honor comfort, creativity, and that moment when underwear feels like more than underwear. At Underwear Expert, we believe what’s underneath should lift your form—and your spirit. Here’s to the pair that makes all the difference.
Happy National Underwear Day—wear what feels like you.
