We create these pieces because I want people to have fun, be wild, spontaneous, and romantic... and never take fashion too seriously.
After all, swimwear is your ultimate partner in crime for sun-drenched days and unforgettable nights, living your absolute best life.

To bring this vision to life, we settle for nothing but the best, combining '80s coastal glamour with uncompromising quality.

Every single Reina Olga piece has been handcrafted by skilled seamstresses inside one of Milan’s most storied, woman-owned swimwear ateliers, which we proudly share with some of the world's leading luxury fashion houses.

We know our bikinis are an investment. We deeply respect the value of hard-earned money and the conscious choice you make to buy from us. That is exactly why quality means everything to us.

Reina Olga pieces are truly made to last. They are designed to be mixed, matched, and reimagined over the seasons and across the years, and even handed down. No matter how much time passes, they will always look and feel amazing.

Raised between the still waters of Lake Como, the energy of London, and the peaks of the Italian Alps, Guia took a distinctly unconventional path to fashion.

She famously bypassed university and traded traditional schooling (navigating six different high schools in just five years) for an education built on pure street smarts, sharp intuition, and an relentless drive.

By age 19, she was already working her way up the ranks of the fashion industry. Over the next decade, her career became a masterclass in global adaptation, living and working across a kaleidoscope of cultural capitals, including Paris, São Paulo, Berlin, Los Angeles, and New York.

Shortly after launching Reina Olga in 2014, life took an unexpectedly cinematic turn. She reunited with her teenage crush after thirteen years apart. Today, he is her husband, the brand's CFO, and her partner in crime. The couple settled down in the alpine beauty of St. Moritz, where they now wrangle a six-year-old hurricane of a son, share a bed with a dog who refuses to sleep anywhere but under the blankets, and harbor an obsession with tennis.

During the winter months, the team’s morning routine involves catching the first ski runs down the mountain before heading into the office. It is a beautifully full, high-altitude life, driven by the same wild spontaneity that started the brand, and balanced by a shared dream of one day packing it all up to sail around the world.
