I believe you, but I have certainly owned a few Dolce mainline suits in my time, and they have all been canvassed. I will admit it has been quite a while since I last purchased one though, so perhaps standards have dropped? If that is the case, I retract my comments that they were decent suits. Perhaps they have become like Prada and Gucci, who clearly offer two levels of suits, one level very good, other level borderline garbage. I am surprised though that a major clothing brand would have the audacity to ask $2K for trash.
The one i have from 5 years ago is canvassed, and the ones i checked out at saks were canvassed as well. But it might be different lines cuz they have some "Martini" line and "golden something" or w/e. In my experience with Gucci and Prada their uncanvassed suits/jackets are at the 1.5k price point and their higher level ones are 2-3k sometimes around 4.
I don't think I've ever seen a Gucci/Prada suit over $2.5K, but I'm sure I haven't seen them all.
I have never heard that Dolce (mainline) has more than one line of suits, but that too is possible, or there maybe (lots of) different versions depending how many manufacturers they've switched between.
I think the Dolce suit I had would have been made in 2008-9, so earlier than that (or in the same period but from different manufacturers, as above) they may well have been canvassed.
