Often overlooked and almost always underappreciated, the short sleeve button-down shirt has the potential to be the most versatile piece of clothing in your wardrobe this summer (and "You ain't even know it"). It’s a look that’s tucked away somewhere between ultra-casual and dressy, offering the perfect middle ground for those long, hot summer days when you don’t want your arms to be weighed down in a long sleeve button-down, but you're unwilling to sacrifice your dapper aesthetic by throwing on a basic tee. With that said, though, not all short-sleeve button-downs are created equal—as with most things in life, there are levels to this. So don’t get caught out there in some wack, #dadbod-approved Hawaiian print shirt. Instead, opt for something a bit more, well, cool. Scroll over each individual shirt in the image above to peep your options.
