I think that the clothing corporations put out new "rules" on a yearly basis in order to convince gullible young men to shell out for new (and often preposterous) clothes on a seasonal basis. Some people get confused, and think these are actual rules, even where they clearly conflict with the traditional (read: REAL) rules.* Adding to the confusion are those who confidently express their personal opinion or preference as a rule. Pretty soon, 50 different people are citing 10 different, mutually exclusive rules. No wonder so many throw up their hands and assume that there ARE no rules.
