Is apparently "Never wear clothes that fit. Ever". Just look at how thos shirts give the illusion of a muffin top, and how thos pants sag in the bum. Also, is he wearing DOCKERS??? Those khaki pants look like Dockers to me.
You would think that a man with as much money and status as Paul Ryan could afford a worthwhile tailor, but apparently not. All of his clothes are two sizes to large. I understand how difficult it is shopping for a thin man. I really do. That's why tailoring exists. And Italian cut suits. And fitted shirts. There's really no excuse for this man. On any level.
