now someone will show up with a fused that has an extension in the lapels and that is not a half canvas.
Whether it's called half canvassed or not, if a suit jacket has a canvas in the lapel (in addition to a canvas chest pieice), but not below the midway point of the jacket's front, making the lapel more supple and giving it a nice roll (because it doesn't have an interlining glued to the outer/upper shell fabric that in part makes up the lapel), why doesn't that count for something, Alex? I prefer it to suit jackets with fusing in the lapel. Southwick, BB 1818, HF Ltd., and at least some HSM suits (all that I've looked at, anyway) are made this way.
