Giorgio Armani Black Label (GA BL) is the best Armani has to offer. I personally do not like fit or styling of the typical GA BL suit, but they are well made with nice fabrics and usually (but not always) have a full canvassed construction. I also notice they are still constructed with many of the "hand-made" features one usually associates or takes for granted with the Napoli based tailors, or even Brioni or Kiton. GA BL are good suits for those that like their look or prefer ventless backs (many GA suits are ventless, although you can pick up single or double vents occasionally). Were I interested in the GA BL suit, I would consider anything under $1000 to be a pretty good deal. However, with my eyes on other suit manufacturers, I would not purchase a GA BL for even $200, I simply do not like them well enough to put them on my radar. As for Armani Collezioni, half canvassed typical, better cut than GA BL in my book, but worse quality of course. I would not bother spending $600 on it, if you can get it for $400, power to you, go for it. For $600, you would much prefer other brands like Canali, Isaia, Ralph Lauren Black Label etc - it depends on how well you like the fit and cut of other suits. Armani Collezioni is not Giorgio Armani Black Label - quite different in fact.
