National Underwear Day

At first glance, National Underwear Day may seem unusual, but it carries an important message: promoting a positive body image. Both women and men are encouraged to use this day to appreciate their bodies and connect with others who share the same values. The holiday reminds us that we shouldn’t be ashamed of our bodies—even if they don’t align with modern beauty standards.

History

National Underwear Day was founded in 2003 by Freshpair, an online underwear retailer. At the time, the idea was bold and unconventional, but it quickly gained traction and has only grown more relevant in today’s conversations about self-confidence and body acceptance.

Modern underwear as we know it began to emerge in the 1930s. This era saw the introduction of familiar bra-and-panty sets for women, and more comfortable briefs for men. These garments revolutionized daily life by replacing the bulky undergarments of earlier centuries with pieces that offered more freedom, comfort, and support.

Interesting Facts

• When women’s underpants were first introduced, critics claimed they restricted blood flow to the pelvic area.
• The average American woman owns around 20 pairs of underwear.
• Most women wear the wrong bra size, often due to not knowing how to measure themselves properly.

How to Take Part

Celebrate by embracing your body. Stand in front of the mirror in your underwear and appreciate what your body does for you. If self-love feels difficult, try focusing on self-acceptance and gratitude.

Treat yourself to a new set of underwear that makes you feel both confident and comfortable. Share a body-positive photo on social media if you feel inspired. And if you’re feeling bold, gather your closest friends and throw an underwear-themed party—it’s a fun way to break taboos and promote body confidence.
