My Friend Gave Me a Strict Budget to Give Her Summer Wardrobe an Update—9 Zara, H&M and COS Buys I Chose
From heatwave-ready linen and throw-on dresses to polished summer basics and elevated accessories, these Zara, H&M and COS finds to shop now.
With talk of an imminent heatwave, my group chats have, unsurprisingly, descended into a flurry of sunny plans—beer gardens, park picnics and, of course, the all-important question: what are we actually wearing in 25-degree heat? As ever, the conversation quickly turned to the pieces worth investing in right now, and I found myself replying with a tightly edited list from the three high-street brands I always come back to: Zara, H&M and COS.
Each has its own strength. COS continues to lead the way when it comes to elevated summer basics (the Clean Cut T-shirt remains a quiet hero), alongside the kind of polished, expensive-looking accessories that instantly pull an outfit together. Zara, meanwhile, is where I turn for easy, trend-driven pieces—throw-on dresses, standout silhouettes and those slightly more directional styles that still feel wearable. And H&M? It consistently delivers on beautifully cut linen, from tailored trousers to lightweight shirts that make warm-weather dressing feel effortless.

Collectively, they prove that the high street is awash with pieces that look far more premium than their price tags suggest, if you know where to look. So whether you’re after a fresh pair of linen trousers, a chic summer dress or a raffia bag that works just as well in the city as it does on holiday, these are the Zara, H&M and COS buys I’d recommend right now
