National Plus Size Appreciation Day is observed worldwide every October 6 to celebrate body positivity and the beauty of individuals of all shapes and sizes. The day was initiated by Women Rock, Inc., a nonprofit focused on breast cancer awareness, and was officially proclaimed by National Day Calendar in 2017. The term "plus size" originated from the fashion industry in the early 1920s, popularized by Lane Bryant, and has evolved to encompass a diverse range of body types beyond just those considered obese. Celebrations typically involve activities that promote self-love and respect for all body types, such as clothing shopping, photo shoots, and community events like clothing swaps. Participants are encouraged to share their experiences on social media using hashtags like #NationalPlusSizeAppreciationDay and #PlusSizeAppreciationDay, emphasizing that the message of self-acceptance and body positivity is inclusive for everyone.
