I love the combination of black and yellow. It might be a little bit too bumblebee if done wrong, but when done right I think it can look awesome. I love this dress from Karen Millen combining yellow, black and white (£110):

yellow-karen-millen

Another new dress from Karen Millen is this black and white pencil dress (£175):

karen-millen-stretch-satin

Don’t you think that would look great with a pair of bright yellow pumps?
