John W. Nordstrom Wool and Silk Blazer Men's 40S

This is an absolutely beautiful, sleek, classy silk and wool blazer in virtual mint condition that would cost several hundred dollars new. I love it and hate to part with it, but it's just half a size too big for me. It's 40S on the label, but see pix for measurements. Feels more like a 40R, maybe even a 41. It's black and white checks in the pix, but it definitely conveys a blue hue.
