Sure, you can wear sneakers with a suit. Do it the right way, and you'll strike that perfect balance between debonair and devil-may-care. Do it the wrong way and you'll look like Jon Cryer in the '80s. So as not to come across as a douche or a slob, keep things as minimal as possible, and spend a decent amount of money.
