If we had to guess, we'd say Zara is the most popular fast-fashion retailer among royals. We already know Kate Middleton is a dedicated fan, but Queen Letizia of Spain also knows how to find the chicest pieces at the cult-favorite store. For an event at the Zarzuela Palace on Tuesday, the impeccably dressed royal wore Zara's Printed Midi Dress ($90), which is simply perfect for fall.
Her support for the brand makes sense: Zara is arguably the most famous brand from her home country. Princess Victoria of Sweden, on the other hand, is partial to Stockholm-based chain H&M. While royals often support up-and-coming local designers too, we can't blame them for paying allegiance to their country's best fast-fashion chains.
