Noodles, there's nothing wrong with wearing that shirt with that suit. The neat looked better than the stripe, though. Although CM stated his opinion emphatically, that shouldn't give it any more weight than others. Ultimately, though, if you don't like the combination, then don't wear it.
I don't understand this notion that shoes truly reveal the character/quality of a person. This seems more a reflection of the priorities and predilections of the viewer than anything else.
