National Bikini Day History
National Bikini Day celebrates the popular two-piece swimwear garment, the bikini. This day is an opportunity for bikini wearers, swimsuit designers and enthusiasts to appreciate the versatility, style, and confidence that the bikini exudes. As a fashion symbol that represents freedom and empowerment, National Bikini Day encourages the appreciation of the bikini in all its forms.
The history of National Bikini Day traces back to its origins in France post-World War II. First introduced by French designer Louis Réard on July 5, 1946, the bikini was initially considered scandalous due to its revealing nature. Over time, it has become a symbol of popular culture and fashion, embraced by people of all ages, shapes and sizes. In the United Kingdom, bikinis have been an enduring presence in beach and swim fashion, with British women donning the two-piece swimwear since the 1950s. Iconic British figures such as Bond girls, Ursula Andress and Halle Berry, have further added to the bikini's popularity and appeal.
National Bikini Day can be observed by sharing pictures of favourite bikini moments on social media, trying on new bikini styles or simply heading to the beach. In recent years, campaigns encouraging body positivity and inclusivity have helped shape National Bikini Day into a celebration of all bodies that sport bikinis, whether it's at the beach or by the pool. National Bikini Day takes place annually on the 5th of July.
