Grab your sunscreen—it’s National Bikini Day this July 5, and it’s the perfect opportunity to head to the beach. National Bikini Day celebrates the anniversary of the invention of the two-piece bathing suit. Due to its risqué design, the bikini was slow to be adopted—but it gradually gained traction when film stars like Ava Gardner and Brigitte Bardot started to wear bikinis on public beaches and in their films. It’s certainly one of the greatest inventions of all time, even though its beginning wasn’t quite explosive. (Ironic, because it’s named after hydrogen bomb testing that was conducted at Bikini Atoll in the South Pacific during World War II.) Get ready to celebrate this summer icon with us!

National Bikini Day Activities
Buy a new bikini
Treat yourself—you can never have too many bikinis. But don’t just get the same old one: try a new pattern or color. Summer is just getting started, and so is your shopping spree.
Throw a bikini pool party
Themed parties are so much fun. Grab some bikini-themed decorations at your local party supply store and invite your friends over for some pool playtime. Don’t forget the sunscreen!
Put on your favorite one-piece
Bikinis are fun, but even we have to admit that they’re not for everyone. If the bikini isn’t your thing, that’s okay. You can still join the fun! Put on your favorite one-piece and join the pool party.
Why We Love National Bikini Day
You can show off your fashion sense
Fashion is a great way to express ourselves—the bikini is just another outlet. They come in all different colors, shades, and styles. You can go nineties with a halter bikini, rock a tankini, or even try on a skirtkini. You can mix and match bottoms and tops, stripes, and colors. So what’s your bikini style?
It gives you a reason to head to the beach
No one ever needs a reason to escape to the beach, but it’s always nice to have an excuse. If anyone asks you why you’re not at work, it’s because today is National Bikini Day!
They go with the coolest accessories
Accessories can make or break a look. With the right amount of bling, the perfect coverup, and some stylish shades, you can turn your bikini into a bona-fide summer look! Is that a celebrity, or is it just you rocking the beach?
