To wear or not to wear a belt

What is the rule of style? Is it okay not to wear a belt with a suit or dress pants?

If you are short

Absolutely! Gone are the old school days when belts were mandatory. You do not have to wear the belt at all times. If you are short, not wearing it will make you look taller.

If you are tall

On the contrary, if you are tall, wearing one is a good idea. This will cut off the elongated effect of your figure.
