7 Zara, H&M and COS Staples Im Adding to My Summer Wardrobe

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.

Perfectly balancing on-trend appeal with an equally timeless aesthetic, I consistently turn to these three high-street heroes for designer-passing pieces that will stand the test of time. 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.

7 Zara, H&M and COS Buys I’m Adding to My Summer Wardrobe

1. Midi Dress

Style Notes: Dress season is finally here, and a midi iteration acts as a throw-on style that you can take from day to night with ease. Simply swap out your flat sandals and raffia bag for a pair of kitten heels and a statement clutch.

2. Minimal Sandals

Style Notes: With sandal season in full swing, fashion people turn to pared-back iterations that look chic and put together but also come with a sense of ease that makes them perfect for everyday styling. No matter the colour or fabric, a pair of minimal sandals will add instant polish to all of your summer outfits.

3. Blouse

Style Notes: If you’re a regular reader of Who What Wear, you’ll know how much we love a blouse in the spring and summer. Dressier than your average tank or tee, but still feeling wearable enough for casual occasions as well, this pretty top style will add a touch of elegance to jeans, linen trousers or even capri pants this season.

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.

5. Woven Tote

Style Notes: I cannot wait to get my woven bags out this season. Whether I opt for a beach-ready raffia style or a sleek woven leather iteration, it’s a structure thats timeless and versatile, but also comes with just the right amount of edge to add interest to my otherwise very simple look.

6. Linen Shirt

Style Notes: A button-down shirt will serve you well regardless of the season, but as the temperature starts to rise, I’ll be swapping out my classic cotton iterations for breezy linen that can be worn with matching line trousers, jeans and midi skirts alike.

7. Straight Jeans

Style Notes: With slim-fit denim replacing the baggy and barrel silhouettes that dominated last year, straight-leg jeans are back at the forefront for polished dressers. 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.
