A professional in curiosity for journalism, she began delving into the world of culture and trends from a very young age. Her grandmother was a seamstress and her father a photographer and man of letters, but she opted for writing and worked with the first independent magazines in Barcelona, including Ab (A Barna), Hache magazine and Mondo Sonoro, as well as a brief time as editor of fashion magazine Go mag.
When she finished her degree in Journalism at the Autonomous University of Barcelona, she moved to Brussels, where she worked for the European Union and began studying Fashion Photography and Styling at the Cambre École des Arts Visuels. Meanwhile, she continued writing for several magazines and the Cultura and Dominical supplements for newspaper AVUI. In 2007, she returned to Barcelona and began working as head of Press for the publishing houses Columna, Destino and Planeta in Catalan. Later she was in charge of organising and managing communication for the RBA International Prize for Crime Writing in 2009.
Her passion for fashion, cuisine, travel and interior design was still strong and in 2010 Anna Tomàs began freelancing, writing for La Vanguardia, El Periódico, Lonely Planet Traveller, Objetivo Bienestar, Gastronosfera and Grazia Italia, among others. At the same time, she joined the faculty at the Istituto Europeo di Design di Barcelona, teaching classes in English (in collaboration with the University of Westminster) and in Spanish in the Fashion Department and for postgraduate courses. Her courses included History of fashion, Styling, Magazine publishing and Contemporary trends and iconography, among others. Over the past two years, she has also been an assistant professor in the Department of Hispanic Philology at the Universidade de Lisboa.
She has written a young adult novel entitled Florència a la maleta (Columna) and translated letters from Dalí to Picasso from French into Spanish, for the essay Picasso y yo (Elba).
