  na-adjectiveCovers 'polished' in the sense of refined, elegant appearance or behavior. Use it for people, clothing, manners, or interiors that strike you as tasteful and gracious rather than showy.

• 技巧的ぎこうてき

• 洗練されたせんれんされた
  expression, prenominal modifierCovers 'polished' meaning refined and sophisticated, as a result of careful development. Fits polished writing, style, design, or a polished, worldly manner.

For people, manners, or style, 上品 is the usual choice; for writing, performance, or skill, 「洗練された」 conveys sophistication, while 技巧的 stresses technical accomplishment and is often only a marginal fit for 'polished'.
