/fa/ - Fashion

fellas, i need help. i live in cold climate and i have a black coat i wear in winter (like picrelated). currently i only own blue and light blue jeans. i was thinking of buying a pair of black jeans too. i'm looking to make an outfit that is not dressy but not casual either, something in the middle of formality spectrum, slightly under business casual.
now the question: what sort of shoes do i wear with my outfit? should i go for black or blue/light blue jeans, and what color shoes should i get? ideally for fall/winter but it if its just winter its fine.
