+1. Versace ALMOST succeeded in setting a "lifestyle" brand early on, but (as I said earlier in the thread) the aesthetic simply couldn't connect with the audience RL did, nor be at a pricepoint where it could work.
But, even in the 1980's, Versace was another brand that you can almost think of an idea or "theme" before you think of an actual item: sun drenched beaches, tanned chiseled men and beautiful women on a yacht, exquisitely died silks flowing in the breeze, etc.
This aesthetic became something of a gimmick in the mid-late 1990's (due largely to the shift to minimalism AND Gianni's untimely death) and never really recovered, with the "lifestyle" brand shifting from very luxe upscale to "aging footballers with too much suntan lotion and Russian mobsters with too much gold jewelry."
edit; by the way, if we're going to add brands like Sulka or others that influenced color, tone, or pattern, then brands like Etro or Byblos would be equally valid, the former for introducing a wide range of patterns into classic menswear and the latter for the shift toward subtle uses of bright solids. Not, I'm not arguing for their inclusion, but only to say that I think a case could be made why they (esp. Etro) would be a better fit than several of the others mentioned.
