I've got a pair of Loake Victor (Derby shoes) in tan colour which I'm planning to wear with a white shirt with light blue/aqua vertical stripes and a navy 2 button blazer. The belt will be matching the colour of the shoes however I am stuck with the trousers and socks colour. I have heard that the shoes should be darker than the colour of the trousers and the socks should match the colour of either shoes or trousers. Do these rules apply in my case? If so what colour should my trousers/jeans be? Below is a picture of the items I'm wearing. PS: I'm assuming this is the right place for this type of post?
