A waistcoat was an everyday clothing item for a man during the American Revolution. This cut hits the wearer at the waist and the vents in the back and sides are both fashionable and comfortable. These linen/cotton (80/20) waistcoats are cool in the summer and fashionable all year round. They also have the added benefit of working pockets.
I liked the overall item, although I would have preferred an option to add additional stitching surrounding (a double-bound) the working for the button holes on the front of the waistcoat for better durability, especially with linen which can unravel easily.
