How do I put on a belt buckle?

Do I need to buy a special strap on belt that can hold my belt buckle?How do I put on a belt buckle?Keeper - On back of the buckle the part that is a metal %26quot;loop%26quot;. You put the belt through this part and double the belt back, snapping it to hold the buckle in place. Normally buckles have the keeper on the side towards your left hand as you are wearing the buckle, but sometimes the keeper is on the right side - more of a tradition for women's belts.
