Pleated pants make your butt (and your stomach) look bigger than they really are.

Hawaiian shirts are ok depending on how colorful the fabric. I've seen orange ones that you can use as a safety vest on your walk arounds.

Cargo pants are nice, I think.

Soul patches are so ..... gross. I'm glad it's outdated.

Cowboy hats are ok as long you leave them on to cover your bald head.

I don't know why the author lists the faux pas like that. Perhaps he wants us to buy his book.
