Every year on August 5th, guys around the globe drop their trousers to celebrate one of the most underrated dates on the calendar…National Underwear Day.
While it might sound like just another quirky internet holiday, the history behind August 5th is all about body positivity, breaking taboos, and celebrating the base layer that works harder for you than anything else in your wardrobe.
Here is the backstory on how National Underwear Day came to be and how to celebrate it properly with BOX.
How It All Started
National Underwear Day was officially founded and branded back in 2003. The goal was simple; bring a hidden, everyday garment into the spotlight and encourage people to embrace their bodies with confidence.
What started as a clever campaign quickly transformed into a global movement celebrating self-expression and top drawer style.
Flash Mobs, Times Square, and Breaking Records
In the early days of the holiday, celebrations were anything but subtle. The founders organised massive public gatherings, most notably taking over New York’s Times Square, where hundreds of models and everyday people marched through the streets in nothing but their briefs, trunks, and boxers. In 2013, revellers even attempted to set a Guinness World Record for the largest gathering of people in their underwear!
From Wardrobe Afterthought to Style Statement
Beyond the headline grabbing flash mobs, August 5th was created to challenge a bad habit most guys share, treating their base layer as an afterthought. For decades, men’s underwear was functional, boring, and hidden away. National Underwear Day shifted the narrative, turning the base layer into a core piece of daily fashion engineered to boost posture, comfort, and athletic performance.
The Modern Way to Celebrate
You don't have to storm Times Square in your waistbands to mark the occasion this August 5th (unless that's your thing). The modern way to celebrate is much simpler. Audit your top drawer, toss out the faded, stretched out cotton rags holding back your physique, and replace them with gear engineered to lift, support, and show off your hard work.
