What is National Bikini Day?

National Bikini Day commemorates the invention of the bikini in 1946 by Parisian designer Louis Réard, and celebrates fun in the sun and the freedom to choose one's own swimwear. Before its arrival, swimwear was strictly modest—"beach police" once policed hemlines—so the bikini marked a cultural turning point toward personal freedom and body confidence.
