Every year on August 5th, millions around the world shed the stigma and embrace their inner confidence on National Underwear Day. This fun yet meaningful day celebrates more than just fashion — it promotes body positivity, self-confidence, and awareness about the intimate wear we all rely on daily.

In its early years, the event gained widespread attention through public events in New York City, including underwear parades in Times Square. Models, influencers, and everyday people participated in spreading awareness and challenging societal taboos around lingerie and men’s underwear alike. Since then, it has grown into a celebrated movement encouraging confidence and comfort.
