Pairing opposing patterns is a fun way to amp up the interest level in your outfit. An old stand by is stripes and leopard; rule of thumb is groups patterns with similar colour schemes so the patterns complement each other, not compete. In this outfit- black, white and brown/caramel are consistent in different ways, so it all goes together without having to be matchy-matchy. I would also throw on a big red lip with this look, to give a pop of colour.
