National Little Black Dress Day is observed on September 1, promoting awareness of stroke prevention and cardiovascular health, particularly among women of African descent. Participants are encouraged to wear their little black dresses (LBDs) and share their experiences related to heart health on social media using the hashtag #LittleBlackDressDay. The day aims to raise awareness, encourage screenings, and promote heart-healthy lifestyles. Organizations such as the American Heart Association and the American Stroke Association often partner with corporate sponsors to support fundraising initiatives and educational campaigns throughout September. Additionally, brands may launch limited-edition merchandise, with proceeds benefiting women's health causes. This campaign highlights the importance of community involvement and personal connections to health issues.
