With W.W. Chan touring soon, I am going to tap the collective SF-brain power: I intend to commission a solid light-grey spring/summer suit. I am set for the details, but I am still not settled on the fabric choice. So, Are there any details (weaves, etc.) to look out for in order to get a lightweight, but yet robust summer wool suit? Are there any swatch books for spring/summer wools I should look out for (some things I have in mind at the moment are Scabal's Appeal Bunch, Minnis' Fresco, Dormeuil's 15.8)? I will be glad about any comment or idea.
