Briefly, Classico is much better than Collezioni. Classico is the elite of the Giorgio Armani mainline, whereas Collezioni is a diffusion line (20% less expensive.) Canali Proposta is their younger, more stylistically advanced line. Canali Milano is the mainline. Hugo Boss suits, except for the Baldessarini line, are fused front and largely machine made. By and large, so are all the suits you are looking at except for some of the Classico line, so it's time to reconcile yourself to the idea, unless you have the cash to get a handmade suit from the likes of Brioni or Kiton, which very few people do, and look fine regardless. The Armani suits are made Vestimenta S.P.A., which sells suits under that label in North America, and under the Hilton label in Europe. Hugo Boss contract suits from a variety of factories. The difference between a well or ill-fitting suit, as Flusser writes (and you all know I'm not a big fan), lies principally in the design and fit rather than the construction, which is invisible except to exceptionally discerning eyes. I would advise that you put away your prejudices go down to a good mens store or to a specialty department store like Barneys or Saks, and try on suits until you find the one that fits you and you can afford. I would advise anyone against buying suits on Ebay. My experience is that you should always buy suits only after trying them on.
