It's hard to go wrong with a linen suit for summer. If you already have a darker blue linen suit I would go for the khaki for a totally different look. I have a suit made with W Bill 60136 and I absolutely love this colour, also get lots of compliments when ever I wear it.Here an image
I've had the grey and navy made up, although is a heavier weight the hopsack finish makes it breathable. It's one of the nicest hopsack i've seen, idea for traveling it doesn't crease easily even my tailor commented how great this cloth is to work with.Here an image I've posted here earlier.
