A couple of weeks ago, I had a transatlantic flight–Las Vegas to London. I wore cat slippers.
This may seem in direct conflict with my general praise of dress codes, but they aren’t contradictory.
The purpose of a dress code is to do two things:
Set a standard, so people know what you expect of them Demonstrate your company brand
So, considering I was taking an overnight flight surrounded by people in pajama pants, I figured that slippers were okay for the plane.
