Queer identity research largely overlooks wearable technology. Most work exploring sociocultural considerations of wearable technology determines what is "socially acceptable" based on privileged bodies, excluding queer perspectives. We address this by establishing the foundations of a knowledge base for wearables that support queer expression. We conducted a two-phase qualitative study exploring queer expressive practices and wearable technologies through 16 semi-structured interviews and 15 body mapping workshops with the queer community. We observed themes framing the queer community's understanding of queer expression, wearable technology, and wearable technology for queer users. Providing discussions on current trends in queer expression and wearable technology use, along with design considerations, our work enables the creation of wearable technologies that offer meaningful user experiences for the queer community.CAUTION: This paper discusses topics that could trigger those with histories of homophobia, transphobia, gender dysphoria, racism or eating disorders.
