I'd love red pants. Have brown boots, have white top, have checked scarf and plain red scarf even, I have brown jacket but different. Just need the red bag too (although if I go the plain scarf and black boots, I can go my tartan bag).
Love this look except for the clunky, stub toe shoes. They look like work boots and just don't work for me with this classic outfit that deserves classic pumps even boots or coordinated sandals of various heel heights.
