'perfect' is the definition.
(a utopia is a perfect society)

I don't understand how the rest of the clue works.

(Other definitions for utopian that I've seen before include "Of an ideal existence" , "Just perfect as in Thomas More's fictional country" , "Impractically idealistic" , "in a dreamy state" , "Of Thomas More's perfect place" .)

I've seen this clue in The Irish Times.
