Can you qualify “unique”? In its original meaning, you shouldn’t but if Grammarist is right…
… we were fairly unique, the sixty of us, in that there wasn’t one good mixer in the bunch.—J. D. Salinger
… then of course you can! How uniquely you use it is up to you! Isn’t language wonderful…? Merriam-Webster and Cambridge Dictionaries have your back!
