Cultural Tip
In everyday French, "C'est pour quelle occasion ?" is perfectly natural and informal. In a more formal setting you might say "Pour quelle occasion est‑ce que c'est ?" or simply "À quelle occasion ?" Note that "occasion" can also mean "opportunity" in other contexts, so be sure the surrounding conversation makes the meaning clear.
