A new survey of 550+ C-level and senior executives reveals that most “suits” no longer wear suits to work, prompting ABC News to say that “corporate ladder climbers” should consider emulating the boss and not wearing a suit.

Other habits of successful CEOs, according to the survey: brown-bagging lunch or skipping it entirely, participating in company happy hours, and wearing navy blue (for men) or black (for women).

Obviously, what will get you a promotion in your company depends on your company culture, not just on what a survey says you should do. It probably won’t hurt to wear the suit.
