Recent Italian teen TV series exhibit one feature that has preoccupied fans and fashion bloggers alike: the centrality of costuming. Close analysis reveals how costume design in Italian youth television functions not only as a means of promoting fashion trends and aesthetics but also as a singular vehicle for expressing the protagonists’ struggle to negotiate their shifting identities and to visually configure the self in a hypermediated world. From the use of high fashion as means of self-expression and personal transformation in such series as Baby (2018–2020) and We Are Who We Are (2020) to the subtle stylistic references in such programs as Zero (2021), Summertime (2020–2022), and SKAM Italia (2018–), costumes thematically channel issues of gender, sexual identity, race, and class. This contribution examines significant fashion motifs in these programs to explore how, through costuming, contemporary teen series hold the potential to offer more nuanced visions of adolescent identities in Italy today.
