This thesis explores how self-identified “infinifat” people, defined as those larger than a US woman’s dress size 32, access commercially available fashion and how their lack of access to clothing shapes the performance of their fat identity. Through semi-structured interviews with infinifat subjects and a secondary discourse analysis of “superfat” narratives in popular texts, this research finds that a lack of clothing options reinforces the stigma and discrimination experienced by those at the largest end of the fat spectrum. Particularly, the lack of clothing available to superfat and infinifat people restricts access to social spaces and economic opportunities. While this research draws attention to ways in which my infinifat participants are “hacking” fashion to suit their needs and using social media to advocate for inclusion, the fashion industry’s unwillingness to create clothing options for superfat and infinifat people, supports the perception that being really fat is really bad.
