, clothing is an important part (perhaps the most important part) of characters' appearances and how they display their identity and social standing. In the opening scene, the different people under the church portico are able to discern each other's social class particularly by their clothes. Pickering
is easily recognizable as a gentleman, whereas Eliza
is easily identifiable as a poor flower-girl. Because of this, clothing is naturally an important part of Eliza's transformation. In Act Two, after she changes clothes, her own father doesn't even recognize her at first—and this is before she even begins to act or talk differently. Mr. Doolittle's own
social transformation is also symbolized by clothing. He arrives at Mrs. Higgins'
house in Act Five dressed like a gentleman, and Higgins assumes that this cannot be Eliza's father, whom he met earlier. The importance of clothes in the formation of one's social identity suggests that such identity is rather shallow. Indeed, a central ambiguity in the play is whether one's identity can really be changed by learning to speak differently or putting on a different outfit, or whether this is merely a façade that covers up one's true, unchanging identity. This tension comes to the forefront in Act Four when Eliza asks Higgins whether her new, expensive clothes actually belong to her now. Behind the question of whether she is or isn't the owner of the clothes, Eliza also wants to know whether her new, upper-class identity is really hers, or whether it is just a role she is playing, a costume she is wearing but will have to give up eventually. Clothes thus symbolize the importance of appearances in establishing one's identity and class, while also questioning how deep this kind of social identity goes.
