Why do old men wear high pants?

For the same reason that one day there will be young dudes with pants that come up above their navels, who will wonder what it is with old people wearing pants so ridiculously low.

They'll wonder if the old dudes with low pants have any idea how stupid and badly proportioned they look.

It's about what's in fashion, what's not, what was when you were younger, what you feel comfortable in and what you think looks best.
