If you want to look sharp in a suit, get it custom made by a good tailor and don't fall for all those high end fashion names, they're great marketers. Off the rack suits never worked for me, although they look good, they never look great.
Personally, I still like Lou Myles, now owns a factory with a front end store in Concord. He used to own a store on Yonge St., downtown, but many years ago sold out and moved up north. Lou is world renown and was well known for making suits for the rich and famous including Frank Sinatra, Muhammad Ali, etc...., he still the tailor of choice for many famous people and makes a lot of private label suits for high end brands. He will also make you a custom suit, cost in the thousands and he's still a great tailor, even at his age.
