My own take on tan shoes.
Suits - they must be light colored suits; tan, light grey, white, taupe etc.
Odd jackets - either very light colored pants or a northern lights fit. I don't believe using a similar color value tie is sufficient to balance the stark contrast tan shoes provide in a dark ensemble. But like everything there will be exceptions
Both Lucianos suffer from not closely adhering to Sander's principle. Ties need to be darker
