كل اللى يعجبك و البس اللى يعجب الناس
Koll elli ye'gebak we elbes elli ye'geb el nas
Translation: Eat what you like and wear what other people like.
Meaning: Do what you want, when other people are not involved, as in culinary choices. But when other people are involved, as in sartorial choices, show some courtesy. Despite its nod to conservatism, that proverb's assertion of the boundary between personal and public space is so unequivocal, and increasingly desirable.
