Most of the RTW ones that I've seen (eg. at The Bay and some other stores) are totally fused but I've seen some at Rego that are made in Italy and apparently they are half-canvassed. I was told that the ones made for Harry Rosen's MTM are half-canvassed too. I think you'll be looking for $1200 and up with Zegna fabrics for MTM. Samuelsohn (full canvassing) is better value in my opinion. However if you are interested I know a tailor who could make amazing bespoke garments (crow-feet canvas basting, hand pad-stitching on the underlapel, lapel pick-stitching, hand-attached shoulder, armholes, collar, hand-made button holes, and even the lining is hand-felled) with the pricetag of 2/3 of your recent Armani's. Constructionwise I think it's better than Brioni or possibly even Kiton, however I was told that if you want Armani drape he would advised you to get real Armani. Just message me if you're interested. Full disclosure: I have seen the works but I still haven't tried him yet.
