In French, if I want to make an uplifting poster that says “You are beautiful” and direct it at women, generally, who see the sign, would I say “Tu es belle” or use the more formal “Vous êtes belle”? Is there a more appropriate way to get that message across? I read somewhere online that using the formal “vous” to call someone you don’t know beautiful would come off as forward and rude, but I’m just trying to make a poster reminding women that they’re beautiful.
