How do you use a belt buckle?
The belt usually has a clip or ring that is on the left side (as
it's worn) of the belt buckle. Before putting the belt on, put the
length of the belt through that clip, then put the belt on. The
small nub you'll find on the right side (as it's worn) of the belt
buckle will go into a free hole to keep the belt buckle in place.
If you have a detachable belt buckle such as a western belt, then
the belt and the buckle are sold separately. If that is the case,
then the belt will have a snap that will open the end. The buckle
has a metal ring on the inside that the end of the belt will go
through.
