Why do you people hate suits so much? What's wrong with wearing fine clothes and looking sharp?
People say they're uncomfortable, but if your suit is uncomfortable you've just chosen the wrong suit. Same with your shirts. And if your tie is uncomfortable, learn to tie a knot better.
People who say we should do away with the suit are arguing to do away with centuries of evolution in professional men's attire. It's like arguing that we should trash art or literature, or that we should stop using cutlery and just use our hands.
