WHY FIT IN WHEN YOU CAN STAND OUT!
For looks when you want your belt to make a statement and stand out while complimenting your style it’s best to go for a belt of a contrasting colour, texture or pattern. You could even try and get your belt to match your shoes which is a great rule of thumb when creating that killer combo look.
For instance the red croc belt would go well with either deep red loafers or shoes to match the dark blue shirt or cream trousers.
I tend to go with convention on this one. The belt should coordinate with your shoes, if not by colour than by style.
