Suits, in the summer? Sure, they're sometimes necessary but they never really made sense. If you don't have a dedicated summer suit, the three-season variety can bring the suffering with stiff fabrics and multiple layers. With the relentless heat, it doesn't matter how breathable your blazer claims to be, it's rarely comfortable once the temperature rises. Which is why more and more guys are starting to realize that there's a better, more seasonally appropriate alternative: the matching set. These are coordinated combos—think camp-collar shirts or workwear-inspired shirt jackets with matching trousers or tailored shorts—that offer the same visual cohesion as a suit, without any of the formality or fuss.

The best part? You don't have to sacrifice style to stay cool. Today's matching sets come in soft, lightweight fabrics like linen, seersucker and cotton poplin, with cuts that are relaxed but still refined. They're ideal for everything from low-key weddings and summer Fridays to rooftop drinks and vacation dinners. It's the kind of look that says, “I've got it together,” even if you're just trying to beat the heat.
