Canali makes a fantastic suit, but I like my Samuelsohn almost as much and it was about $500 less.
@fulano - whatever brand you end up getting, the biggest thing to look for is making sure you are getting a full canvas suit - most people's experience wearing a suit is limited to fused and half canvas construction suits, which don't drape as well, so they don't look as good and they don't last as long either. Then, make sure you get the suit tailored to your body. A properly tailored, full canvas suit, not matter the brand, will look and feel great on you.
