KaDeWe might not be what comes to mind when you think of Acronym but they do stock it besides brands like Rick Owens, Undercover and Veilance.
You could also see if VooStore has anything you like. Might as well check out Markthalle 9, grab a slice of pizza from Sironi and walk to Gate194, if you're there. They have a curated selection as well, even though they don't have much stock in store.
