In new situations, I look carefully at appearances. In familiar ones, I glance.
Things do not pass for what they are, but for what they seem. Most things are judged by their jackets.
There is no reliance to be placed on appearance.
Outward appearances mean everything.
You chose books, I chose looks . Now see the difference?
Barba non facit philosophum
A man with a good coat upon his back meets with a better reception than he who has a bad one.
All men's faces are true, whatsome'er their hands are.
