I just picked up a black, mock-neck, zip cardigan. So far, I've been wearing it mostly with tshirts or henley shirts underneath and chuck taylors for shoes. I want to wear the sweater with some button down shirts and I don't think chucks would be that suitable for shoes. I'd like to pick up another pair of shoes; either dress boots or moccasins. I have no clue what color to get though. I definately don't want black boots or shoes but I don't think brown would go that well with black. Any suggestions?
