What is the author's style in Barbie Doll by Marge Piercy?

A narrative poem written in free verse [verse having irregular meter, or rhythm that is not metrical], "Barbie Doll" can be read as a parable of what often happens to women in a patriarchal society. Parables are short narratives with a moral. Well-known parables are found in religious texts such as the Bible. The moral of Piercy's poem also functions as a warning: it urges readers to be aware of the ways in which society shapes our (gendered) identities and urges women not to compare themselves to idealized notions of feminine beauty or behavior.
