Though they look rugged and heavy, these cotton denim shirts are surprisingly light. And surprisingly versatile. Perhaps that's why we're seeing them everywhere this summer. They're able to be dressed up with a blazer or under a cotton suit, or worn casually untucked, sleeves rolled and undershirt showing. The durable button-downs make an ideal travel piece that can be repurposed and worn as a jacket throughout your trip. And the best part is that they come in a handful of price points, fits and finishes—from inky blues to worn-out Western details—so you're bound to find one that fits your style and budget.
