Michelle Williams shares photo of another passenger's bare foot on her first class flight

My mama raised me to always cover my feet while traveling by plane. Even if you're wearing sandals, you're allowed to commit the cardinal fashion sin under this one circumstance. Why? Hygiene!! I mean, in this day and age I don't fly without a mask on, to protect others and myself. So the same principle applies for keeping your feet covered. Well, Michelle Williams just had to take a couple days off from her Broadway show, Death Becomes Her, to fly to Chicago for a family funeral. And someone was sitting behind her on the return flight - in first class - whose mama did not raise him . . .
