||Treating the consumer as an individual, studies of Chick-Lit have usually taken consumption to be a matter of the relation between things and persons who buy and use them. Commodities are useful in so far as they contribute to the fashioning of their self-identity. Availing itself of Judith Harris’s theory of social categories and group contrast effect, the thesis argues instead that identity formation is not a personal matter but social and interpersonal process; that one’s identity is realized only in social recognition. To the extent that commodities contribute to self-fashioning, they do so by creating the social conditions and social relations favorable to the realization of one’s identity. To demonstrate the social and interpersonal process of self-realization, the thesis analyzes the relationships Becky Bloomwood has with other people in the Shopaholic series by the British author Sophie Kinsella. Chapter one gives an account of Harris’s theory so as to pave the way for Becky’s relation and interaction with other Shopaholic characters in the following chapters. Chapter two discusses how Becky’s multiple identities are variously realized through her relations to, and differences from, traditional women and women of other social groups. Extending Harris’s theory of group contrast effect to the conception of territory invasion, the next two chapters discuss how getting into other’s territories or being blocked from them all assist Becky in the process of her self-realization and socialization. The concluding chapter talks about my finding and bring out further research possibilities.
