It's a basic tweed that contrasts nicely with blue / indigo stuff. The heavier wool should be paired with denim and a more textural shirt. The color is neutral enough that you don't just have to stick with blue. I'd say wear it with a chambray shirt, jeans, and a pair of leather boots.Can you provide measurements for the size Large? I'd guess the chest laid flat is between 21 and 23" across, but I'd appreciate confirmation. Thanks!
