National Underwear Day -

Updated on by

Annually on August 5th, we cheerfully acknowledge National Underwear Day - a lighthearted, yet vital tradition. This day aims to highlight the significance of the most intimate layer of our attire often neglected in everyday conversations. Even though it adds an element of fun, the day calls attention to the importance of underwear for providing comfort and maintaining hygiene.

Let’s celebrate this day by embracing body confidence, cherishing our favorite unmentionables, and why not? Perhaps adding some brand-new sets to the collection.

History of National Underwear Day

Established by Freshpair, an authoritative online merchant for men’s undergarments and lingerie, National Underwear Day first emerged on the scene on August 5, 2003. The day was created to publicly acknowledge the role of undergarments in our daily lives. To launch the inaugural National Underwear Day, a festive parade was organized in New York City where models donned stylish bikinis and briefs.

Fast forward a decade, 2013 saw Freshpair attempting to make history on the 10th anniversary of National Underwear Day by breaking the Guinness World Record for the largest gathering of people in their underwear. Times Square in New York City was the designated location for this global spectacle. Although they gave it their best shot, they fell short of the record by just 184 participants.

Throughout the years, the event remained noteworthy, expanding to include activities like underwear fashion shows and billboard promotions featuring models in trendy underwear designs. Well-known personalities like Conan O’Brien, Ellen DeGeneres, and Zac Efron have highlighted the occasion through their television shows and online presence.

The overall objective of National Underwear Day isn’t limited to promoting underwear sales. Instead, it suggests a deeper message that incorporates body positivity and self-appreciation. This event is marked annually every August 5th, reminding individuals to celebrate their bodies and to feel confident in their own unique shape and size.
