I have a Christmas party to go to tomorrow... I am wearing a black sports coat and kaki slacks with a white shirt. What color shoes/belt should I wear? Would a blue shirt look better? What would go with the black sports coat. The coat and pants are the only constants. The shirt/shoes/belt are variables that I will change if needed. Please help!?

Black or brown loafers will go with anything.The khaki slacks, blue shirt and black sports coat will go together. Since it's more of a causal affair wear a woven belt with a pattern or some kind of stitching.
