Hey! I'm going to be cosplaying a character from Shuffle, who wears the basic buckle-shoes. For her, I decided to look for loafers on Amazon, and ended up running across these:
I chose the "Light Pewter", and it came out pretty close to the brown that I wanted. They are rather shiny, but close enough design-wise that I was ok with that. If you don't like these, then simply google "brown loafers". It doesn't really have to be brown leather-imitation is pretty cheap.
