While the lingering chill in the air may still be trying to convince us otherwise, summer is very much on the horizon. Soon, sandals will replace loafers, linen will take over from denim and dresses will once again become the backbone of our wardrobes.
As a shopping editor, I’m constantly asked where to find elegant, affordable dresses that actually look expensive—and while I hate sounding repetitive, I always come back to the same three brands: Zara, COS and Mango. Between them, they’ve quietly mastered summer dressing, each offering something slightly different, but equally essential.
Zara excels at balancing timeless staples with more trend-led silhouettes, from airy cotton dresses and romantic lace-trim styles to elevated holiday pieces that feel far more premium than their price tags suggest. COS, meanwhile, takes a more minimal approach, focusing on sculptural shapes, clean lines and premium-feeling fabrics that give its dresses that quiet luxury appeal fashion people love. Then there’s Mango, which consistently delivers on easy, feminine summer dresses—think soft draping, playful polka dots and elegant occasion styles that work brilliantly for weddings, holidays and everything in between.
