Anyone who knows me will tell you that I’ve never been one to follow trends. I think it’s all well and good to have the latest craze, but to me, looking expensive and polished will always be difficult without having those key capsule wardrobe staples in place. And I find that mastering the art of elegant dressing during the warmer months is even more challenging.
So, with the upcoming summer season approaching, I’ve already started to think about which trusty staples will form the foundation of my everyday wardrobe. And after months of observing what’s trending on the 2026 runways, scrolling on TikTok and Instagram, and spotting street style on my commute to and from the Who What Wear office, I’ve managed to narrow it down to seven versatile staples that I’ll be wearing on repeat this season. And it should come as no surprise that I immediately turned to my favourite high street stores, Zara, COS and H&M, to shop them.

And very quickly, my basket was filled with a myriad of summer staples that are chic, easy to style and, most importantly, look way pricier than they are. And luckily for you, I’ve rounded up items that perfectly fit this description below.
Keep scrolling to shop the seven designer-looking Zara, COS, and H&M staples that I’m adding to my summer 2026 capsule wardrobe.

4. Linen Trousers
Style Notes: When it gets too hot for my wool trousers, I always turn to breezy linen to see me through from now until early autumn. I’m well aware that classic drawstring styles might feel a little too casual, so I tend to opt for more tailored linen trouser styles that can work just as well for the office as they can for a day out with friends.

They lend themselves very well to a smarter style of warm-weather dressing, but they’re also incredibly adaptable, pairing just as well with a simple tank top as they do an elegant blouse.
