Diet Prada is an Instagram account and fashion watchdog group. Created in 2014 by two then-anonymous founders, the account's owners were identified in 2017 as fashion industry professionals Tony Liu and Lindsey Schuyler. Originally created as a lighthearted way to call out similarities in designs, beginning in 2018 the account became a more serious voice in campaigning for integrity and accountability within the fashion industry. In addition to highlighting copied designs, Diet Prada has drawn attention to cultural appropriation and lack of diversity in publishing and fashion companies. As of July 2020, the account had two million followers.
