How to Nail Smart Casual Style This Summer

Smart casual in the summer is all about finding the sweet spot. You want to look like you’ve put in some effort—but not like you’re about to melt. Traditional tailoring can feel like overkill when temps rise, but going full-on casual doesn’t always hit the mark either.

So what’s the fix? Fewer layers, but keep a little structure. You’re aiming for put-together, not buttoned-up.

It’s all in the basics. A crisp polo with proper trousers. A relaxed camp shirt that still looks intentional. Need to take things up a notch? A lightweight blazer does the trick—just make sure it’s breathable. And your shoes? Keep them polished, even if they’re open-toed.

Stick to fabrics that breathe—think linen, seersucker, cotton poplin—and let them do the heavy lifting. Softer tones and summer neutrals like light navy, stone, olive, or white help you stay cool while looking sharp. And don’t skip the small stuff: a belt that pulls the look together, sharp sunglasses, or a watch that feels thoughtful but low-key.
