Whether you’re sunbathing under the scorching heat for those sexy tan lines or taking a daring dive into the ocean, you’ll feel effortlessly sexy, playful, and completely in control of the attention you’re getting.
A brief history
Roughly 15 years after the modern bikini’s inception in 1946, Brazil is credited with their heavy influence in the creation of the micro bikini.
“Known as the ‘fio dental’ or ‘dental floss’ style, characterized by its thong-like design,” Midori Bikinis reports, the South American country coined the Brazilian bikini style in the 1960s. A Brazilian model, Rose di Primo, is known to have sported the first string bikini in 1974, according to Women’s Wear Daily, and the micro style has continued to evolve ever since—with a resurgence in pop culture through magazines like SI Swimsuit and the rise of social media platforms in the 2010s.
The most popular micro bikini looks
Micro bikinis come in a number of different sub-styles. The string micro bikini, micro monokini and micro triangle tops are similar to their common swimwear counterpart (just miniaturized), while stick-on tops apply an adhesive to the body, rather than cover it using fabric.
Why it’s about more than skin
Micro bikinis are a perfect choice for a suit that expresses confidence, sensuality and style. Brasilia Swim lists numerous benefits for sporting this type of suit, including lack of tanlines, speedy drying and poolside lounging—among others.
SI Swimsuit models have raved over micro bikinis this year, deserving their place as a style that’s here to stay. “I like to wear as little as possible,” Jena Sims tells SI Swimsuit.
“I like the tiniest bikini I can have,” Olivia Dunne concurs.
Celebrity and social media influence
The virality of a micro bikini is a key component in its rise to success. Worn by Kim Kardashian and Sofía Vergara—among a number of standout celebrities—the trend is cementing its place in high fashion. Additionally, micro bikinis were a staple of Swim Week in Miami, Fla. this May, according to HOLA!.
Anywhere you look, you can find a micro bikini with common hashtags (#MicroBikini, #BikiniTrend, etc.) for inspiration on Instagram, TikTok and Pinterest.
The Dos and Don’ts
Micro bikinis are the most revealing style of swimwear; therefore, local laws and public decency guidelines in certain locations may limit where you wear them. For example, topless beaches and private resorts may be appropriate, whereas family-friendly zones may be a place to avoid.
Additionally, micro bikinis can be ideal on their own for photo shoots or tanning, but could be layered with cover-ups or other swimwear garments in public locations. As always, be sure to layer up on the SPF when rocking one of these teeny two-pieces.
