The best man wears a small black suit, black slacks, a white shirt without a tie and black canvas shoes (such as converse. Ke Fan. . . ) is that all right?

Hello, leather shoes with upper shoes are more fashionable than canvas shoes, and more suitable for the occasion of the best man. Canvas shoes are too inappropriate and solemn. Of course, I don't know how old you are, because wearing a white shirt gives people a more handsome feeling. If you are about 24 years old, you can wear a black shirt. Don't worry about stealing the show (at least you don't wear a tie). The bride and groom are kings at the wedding. I believe that people's clothes can attract others' attention.
