As we mentioned earlier, Crain’s Chicago Business reports today that workers in some Chicago offices "are being encouraged to dress down to avoid being targeted by protesters” during the NATO summit later this month. “Tenants in the office building at 1 E. Wacker Drive received a memo encouraging them to stay away from wearing suits, urging workers to ‘look like a protester.’”

So, in the interests of keeping office workers safe, here are some tips to help you get dressed for work May 20 and 21.

—Wear a hoodie. Forget anything J. Crew or Juicy Couture—you need something washed out and dingy, preferably in a neutral dark color. Don’t use anything you got at the corporate retreat.

—On the bottom, you could do jeans, but why stop there? Go for the total look with army shorts, cargo pants, or camo pants.

—Loafers and heels are dead giveaways that you work for the Man. Instead, choose beat-up sneakers or sandals, preferably Birkenstocks.

—Tie a bandanna or scarf around your neck, hinting that you might need it later for the tear gas.

—One word: dreadlocks. Or at least bedhead. Maybe don’t wash your hair all week.

—Instead of your briefcase or purse, carry your stuff in a banged-up backpack. Extra points for slogans and anarchy symbols written on it with permanent marker.

If dressing like a civilly disobedient individual offends your sensibilities, you could always try to go incognito as some sort of city worker by throwing on a safety vest over your business casual ensemble and carrying a walkie-talkie. Good luck!
