Nothing feels as good as natural fibres in a shirt. This 100% linen shirting has a nice hand, not too crisp. The stripes are yarn dyed and subtle so you don't need to match them. However, you should ensure that the pattern pieces are laid out perfectly straight along the grainline. The fabric colour reads more as a khaki brown than olive green. Use the swatch as the closest indicator of colour.

The Men's Classic Sport Shirt #202 is perfect for this fabric.
