They ' re not generally open to the public . <| sep |> Smart casual is effectively a nicer version of casual clothes . Something like an OCBD with rolled up sleeves , potentially tucked into chinos with a pair of brown derbies or loafers or something . Business casual is a bit more formal , and you ' d be looking at a button up in a pale shade , tucked into wool trousers with an oxford shoe . Generally , informal dress would be a suit and tie , and formal dress would be black tie , but I ' m sure if people are saying you should wear smartbusiness casual , that they aren ' t meaning black tie when they say formal . I would say the nicest outfit would just be going in between , with the navy pants , light blue shirt , the link just goes to the Lowes homepage , so I can ' t see it . Depending on the stripe it may or may not look good . plain burgundy tie probably wouldn ' t put stripes on stripes , brown belt and brown shoes . not sure why you own a brown belt and black shoes ? you should ideally be matchingGood luck !
