Seersucker
"Seersucker" may bring to mind images of The Great Gatsby and parties in West Hampton, but it is the perfect fabric for a lightweight Summer suit with or without your beachside mansion. Seersucker naturally puckers, creating distance between your body and the fabric, keeping you cooler during those hot Summer days. The Ivy League boys solidified the look in the 1920's and it's been a staple in men's Summer fashion every since.
Most seersuckers have a fine stripe or check pattern woven into them. It's usually hard to see from far away (as in these photos)-- just wear it like you would any other tan/light grey blazer. If you're going to pair it with denim, stick to a white or a light indigo wash. The lighter colors will keep you looking fresh and easy-going. Ditch the tie for a pocket square instead. You'll look polished while still letting your neck breath. I have a harder and harder time wearing ties in the Summer, how about you?
And yes, you can wear a short sleeve shirt under a blazer.... no one needs to know.
