I think Fritzl thinks Mr. Shoegazer is shilling for Maftei & the trunk show he is involved with. Now Butthurt, Mr. Shoegazer brings it to the attention of the forum in a Robinsonesque redux rather than dealing with it quietly.
Just because academia has a casual vibe does not mean you should buy a casual suit. By the best suit, shoes, shirt ties you can even if you are poor. You will always have a need for a suit so get something that is appropriate and flexible for a variety of settings
^This. The OP asked about appropriateness of suit colour and shoes, not about fit. It was answered well above. The threads referenced to support brown over black also support the notion that in formal circumstances, black may indeed be more appropriate and that even proponents of brown shoes might support that notion.Providing general, surface knowledge suit fit advice in the absence of fit pics accomplishes very little.
