Her first fashion contact was in 1992, when Eugenia Silva was 16. She competed in the Elite Look of the Year Award, heralding the start of her career in fashion.
Eugenia Silva grew up in a family of jurists, as the niece of Antonio Hernández Mancha, and she herself graduated in Law at Colegio Universitario Cardenal Cisneros, affiliated to Madrid's Complutense University.
Her career took off when she moved to New York City, chosen to be the image of Oscar de la Renta. With more than 100 appearance on the covers of magazines such as Harper’s Bazaar, Telva, Elle, Marie Claire, Glamour, and Vogue, she has worked with the most renowned photographers in the world, like Mario Testino, Steven Meisel, Arthur Elgost, Bruce Weber, David Bailey and Gilles Bensimon. She has modelled on the catwalk for Giorgio Armani, Prada, Versace, Galiano, Dior, Jean Paul Gaultier, Elie Saab and Carolina Herrera, among others. She currently publishes a monthly column in ELLE where she offers her secrets on fashion, beauty and travel, and a daily photoblog in the magazine's website, called “My Lookbook”.
In 2011, Silva became the new European image for Garnier (L´Oreal Group), and the face of Magnum for the brand's 20th Anniversary celebrations.
Silva has also ventured into the business world with BRAVEN Films, a production company she founded in 2010 together with Frida Torresblanco (who produced Pan's Labyrinth, directed by Guillermo del Toro and winner of 3 Oscars). Their first major project was TREVI, a movie based on the true story of Mexican rock singer, singer-song-writer and composer Gloria Trevi. She has just acquired Can Toni, a bar on the island of Formentera which opened in May 2011 and is located in El Pilar de la Mola.
She was also the model of the Pikolinos Maasai collection.
Silva is involved in various charities, including World Vision. She also collaborates with Médecins Sans Frontières and Plan International.
She is an ambassador for Fundación Plan, an NGO that works to improve the lives of children in 49 countries in Africa, Latin America and Asia.
On 1 April 2014 Eugenia and her partner Alfonso de Borbón y Yoldi had a son, Alfonso.
