You know, other than a few people here, I really don't think most people care what anyone else is wearing on the plane. They're too busy caring where their luggage is, how comfortable their seat is, whether the food is tolerable, whether the plane on time, whether the IFE works, whether they've lost track of others they're traveling with, and whether the person next to them is annoying. They care about the weather, the water, the state of the plane, the annoying pilot's announcements. I have never seen anyone get off a plane and say, "The flight was fine, we arrived on time, the service was wonderful, but I'd never fly that airline/route again because the other passengers just don't know how to dress."
