I'm going to buy a few more suits in the next few weeks to replace some of my wardrobe. I wanted to stick with the full canvas ones, since reading about what that is and its benefits. Cost is less important to me than durability, style, and crisp appearance (if that makes sense). First, who generally makes full canvassed suits? Are Zegnas full canvas? Brioni? etc. Nobody really says if the suit is full canvas or not, so it's hard for me to tell if it is. Is there some way to identify that when looking at a jacket? Second, is it possible to find full canvas suits that also have vents, or are the two completely unrelated? I prefer a jacket with vents, they seem to hold their shape better, although I could be totally mistaken here. Third, I have seen some Brioni jackets where the "lapel roll" makes the 3rd button on the jacket look unusable. Can you use the 3rd or top button on a jacket with a pronounced lapel roll without somehow damaging the lapel roll or negating it? I really like the look of the Brioni jackets and blazers I've seen, and they all seem to have that roll, but I like to button my top button. For some reason I think it just looks cleaner and less sloppy. Do you have any comments, Manton, since you appear to be one of the more authorative members of the forum?
