No Lie—This Throw-On Linen Dress Is the Chicest Thing on the High Street Right Now

There’s no doubt about it—the summer months are my favourite time of year. The long evenings, the warm days, the endless blue skies—each aspect feels energising. And beyond the mood-boosting benefits, summer also brings the easiest dressing equation of all: one great dress + a pair of sandals = a chic silhouette without a moment's thought.
As someone who swears by effortless, throw-on dresses, I dedicate a little time each spring to scouting the best new-in styles. I compare fabrics, fits and price points, searching for the silhouettes that feel both timeless and fresh. This year, however, my usual hunt was cut short—I stumbled upon the perfect summer dress just weeks into the new season.
Crafted from a heavyweight linen-blend fabric, COS's A-Line Maxi Dress (£115) made an immediate impression. The deep chocolate brown shade is an ideal transitional hue—it pairs naturally with the rich, moody tones lingering from my winter wardrobe while also offering a striking contrast to the soft peach and pink shades I’m leaning into for the warmer months.
Designed with a generous A-line cut, the dress has a voluminous yet graceful silhouette that skims the body elegantly, allowing for plenty of movement and breathability without feeling bulky. Subtle pockets add a practical touch, and the true maxi length—just shy of my ankles at 5’7"—gives it an elongated effect.
Easy, chic and pleasantly versatile, I'll be wearing this with strappy sandals for relaxed weekend days, and dressing it up with a slouchy clutch and heels for evening plans.
While I love this in the chocolate brown hue, I've also spotted a pretty apricot style hit the shelves that's well worth a look in if you're trying to weave more colour into your spring rotation. Priced at £115, this isn't the cheapest style on the high street, but honestly, after feeling the fabrication and trying it on, I would have guessed it was far more expensive than it actually is. A versatile staple that makes this case via a cost-per-wear angle; this is the kind of dress that you can turn to season after season.
