 Here are three holiday party outfit ideas. Option one, go with some black watch tartan trousers, a cozy cashmere turtleneck and some suede loafers for a simple classic holiday look. Option two, layer a black watch flannel shirt over a black turtleneck and pair that with some navy corduroy and some suede loafers to live out your Ralph Lauren fantasy. Or option three, go formal with some bold tartan trousers, don't forget the cummerbund and a black velvet dinner jacket for a fun, festive and statement making look.
