There are rules and traditions in classic menswear. Some things objectively look terrible. Some things are objectively inappropriate in certain settings. Something does not become appropriate or look good just because you have different tastes and nobody is going to tell you otherwise, nor should they have to. You're going to get advice on what is appropriate and what people here think objectively looks good (shined oxford shoes with leather soles are the appropriate thing to wear with most suits regardless of your tastes; you may get away with a nicely shined pair of derbys or monks but that's about it). It is great that you want to figure out how to work with your own sense of style, but there are ground rules.
You may not want to hear these things. If you want to ignore what is appropriate and wear something that does not look good, that's your decision. Any poster here reserves the right to tell you it looks ugly and if you see a number of posts saying something looks ugly, you might take that as a form of advice that you should never wear said item again or should not buy said item; I for one prefer honesty to flattery but YMMV. Coming on here and threatening and insulting people is going to do you no favors.
Thanks for the advice on shoes, but I mentioned light grey suit (not dark colour). Great advice!
