Zara is a known high-street favorite among It girls (Olivia Palermo in particular) and yet it has a sneaky secret up its sleeve—sister brand Massimo Dutti, which counts OP and Leandra Medine as fans. While the Spanish label is huge globally (seriously, there’s seemingly a store on every corner in Europe), it’s still fairly new to the US, making it a covetable stop for fashion-girl essentials that fly under the radar. A gold mine for elevated basics from gorgeous blouses to brilliant outerwear, the retailer serves up an equally impressive array of trendy pieces—think playful shirting and pajama-style suiting—all well made and available at a majorly attainable price point. The brand recently made its runway debut at its stunning new flagship in Barcelona—with Olivia and Leandra in attendance. Here, shop the insanely cool outfits the style mavens wore to the show, and preview Massimo Dutti’s gorgeous spring collection.
