Etro 3-piece Suit from Fall 2009 RTW.
To be honest, I never exactly gave much thought to a mens suit until I saw/learnt about how much work and attention to detail went into actually making the suit. I think every guy should own and wear a complete 3-piece suit at least once in their lives to fully appreciate the meticulous work of the tailor behind the suit.
