National Bikini Day marks the anniversary of the two-piece swimsuit in July of 1946. Designed in France, Europeans were eager to partake in this new fashion trend after World War 2, but Americans refused to be so "indecent" until around the 1960's. The bikini stands as a symbol of female liberation from the patriarchal standards of beauty and comes in many shapes, sizes, and colours to fit and flatter every body.

National Bikini Day is observed on July 5th.

We are unable to identify the founder of this specific national day. However, the bikini itself was invented by French designer. Louis Réard on July 5th of 1946.
