The CSC Edit: The Heatwave Clothes I’m Shopping on High Street This Week

The CSC Edit: What to Wear in a Heatwave High Street Style

The heatwave is coming and I refuse to be caught out. Every year I spend the first hot week in black jeans because I haven’t planned ahead, and every year I tell myself I won’t do it again. This is me not doing it again.

I’ve been dressing women for over fifteen years, first in salon chairs, where I learned more about how women actually feel in their clothes than any fashion course taught me, and now through CSC, where I write about the pieces worth spending on and the ones that aren’t. What I know, after all of it, is this: summer dressing fails most women not because they lack style but because they shop reactively. The heatwave hits, they panic-buy something that doesn’t work with anything they own, and by September it’s buried at the back of the wardrobe with the tags still on.

This week I went looking for affordable pieces that solve a specific problem, clothes that don’t crease the moment you sit down, don’t cling by midday, and still look like you made an effort. Three brands, three very different solutions, and one piece I considered and put back. Here is where I landed.

This Week’s Lead Buy: Mango Linen Suit Waistcoat in Ecru

I have been thinking about this for a few days, which for me means it’s definitely going in my shopping basket. A linen waistcoat in ecru works as hard as anything I own. Over wide-leg trousers it reads structured and intentional. Thrown over a slip dress it bridges the gap between dressed-up and genuinely comfortable in a way that a blazer cannot manage in 28-degree heat. The ecru specifically, not cream, not white, sits cleanly against pale skin without washing you out, and it layers with the browns, navys, and blacks I actually wear.

Mango’s tailoring has improved considerably. The construction on this is clean, the fit is relaxed without being shapeless, and linen at this price point is a genuine win for summer. If it holds its shape through the season, it will become a year-round layer.

Also On My Radar

COS V-Neck Midi Cami Dress in Brown

Brown is having a moment and I am fully on board with it. This cami dress sits at exactly the right length, midi, so it reads elegant rather than casual and the V-neck does the work of making it feel intentional rather than thrown on. Viscose moves well in heat and doesn’t cling the way jersey does. I’m wearing this with the Mango waistcoat above and flat mules, and the entire outfit costs less than a single piece from most of the brands I write about in the Worth It? series. That ratio matters.

H&M Lace-Trimmed Viscose Top

I don’t often write about H&M for anything other than basics, but this top stopped me mid-scroll. The lace trim is restrained — it sits at the neckline and cuff without tipping into anything fussy — and the viscose drape is genuinely good for the price. Tucked into tailored shorts or the kind of wide-leg trousers I wear constantly from June through September, it elevates the look without trying. This is a piece that does its job quietly, which is exactly what I ask of anything under £30.

The One I’m Leaving Behind: COS Pleated Cotton-Linen Maxi Dress

I spent longer on this than I should have. The fabric is right cotton-linen, breathable, relaxed and the pleating is the kind of detail that makes a dress feel considered rather than basic. But the drop waist is the problem. Drop-waist cuts sit at the widest point of the hip rather than defining the natural waist, and the effect is one that doesn’t flatter my shape. It’s a beautiful dress on the right body. It is not my dress. If you carry your weight differently or prefer a more relaxed silhouette, this could be an excellent buy the fabric alone justifies a look. For me, it goes back.
