National Shapewear Day is observed worldwide every August 10. Established in 2017 by The Pink Room, a retailer specializing in shapewear and related garments, this holiday aims to celebrate shapewear and highlight its benefits. The day counters misconceptions about modern shapewear, which refers to undergarments designed to temporarily modify body shape for a fashionable silhouette. The history of shapewear dates back to ancient Greece and Rome, evolving from restrictive corsets to more comfortable modern garments made from elastic materials. On this day, individuals are encouraged to wear their favorite shapewear, consider purchasing new items, or gift shapewear to others. Many brands also offer promotions in honor of the holiday, and participants are encouraged to share their experiences on social media using hashtags like #NationalFoundationDay.
