Suddenly, Every Chic Person Is Wearing An Elegant Dress From One of These 3 High Street Brands
The heatwave has arrived, and stylish people are turning to Reformation, Dôen and Sézane for their elegant summer dresses. Shop the best below.
The current heatwave has offered us our first taste of summer, and the sky-high temperatures have led me straight to my dress collection. Easy, reliable and instantly put-together, on the hottest days, I don't have the wherewithal to think about putting together intricate layered looks. Instead, a throw-on dress is the ultimate hot day hack. As someone who only started wearing dresses a few years ago, I've been slowly and steadily growing my collection, but with an expansive summer ahead, it's time to bolster it. This season, I'm turning to the brands that fashion people rely on for the most sophisticated dresses around: Reformation, Dôen and Sézane.
Marina wears the Dôen Ischia Dress (£380)
The binding thread between these three brands is a touch of charm. Whether it's the sculpted silhouettes at Reformation, the delicate embroidery at Sézane or the intricate shirring of Dôen's dresses, the attention to detail makes every style look incredibly expensive. Alongside, a focus on high-quality fabrics makes this trio one to consider first when adding to our dress collections. Breezy linens and airy cotton poplin satiate the scorching temperatures, whilst all are designed to exude refinement, whether thrown on for relaxed summer days or elevated for the evening.
Sara wears the Sézane Odette Dress (£175)
When curating this dress edit, I focused on a few key details. One, as ever, is timelessness. Any time we add a new piece to our wardrobes, we want to make sure that it's going to go the distance, and the quality creations and enduring designs of the pieces below will do exactly that. Next, it's worth considering your summer schedule. Most of these dresses can be styled from city to seaside, but I've also added a few resort looks with intricate fringing in case you're in the midst of holiday packing. Finally, keep an eye out for intricate details that make every piece look like a high-end designer buy. From refined silhouettes to perfectly placed pleats to sweet lace additions, the finer details make these dresses standout from the rest and ensure you'll reach for them every single year. Now, the mercury is still on the rise, let's get straight into the best Reformation, Dôen and Sézane dresses for summer 2026.
