Alexander Wang has been accused of sexually assaulting male and transgender models, including allegedly drugging and groping them.
The 37-year-old designer's accusers went public with the allegations on social media on Monday.
A post by industry watchdog S**t Model Mgmt accused Wang of being a "sexual predator" and asked fashion buyers to boycott his clothing line.
"Alexander Wang is an alleged sexual predator, many male models and trans models have come out and spoken about the alleged sexual abuse that Alexander Wang has inflicted upon them.
"It is important to show your support to these victims by unfollowing Alexander Wang and boycotting his clothing line."
Several anonymous accounts shared stories of alleged sexual misconduct and being drugged with MDMA.
Model Owen Mooney had earlier uploaded a TikTok video claiming he was "touched up" by a "really famous" fashion designer in 2017. Although Mooney did not initially name his alleged abuser, he later uploaded a follow-up video and confirmed it was Wang.
According to editors at WWD, Wang's spokeswoman declined to comment on Tuesday.
However, fashion advocacy group Model Alliance issued a statement on the same day, supporting Wang’s accusers.
"We at Model Alliance stand in solidarity with those who have shared accusations of sexual abuse by Alexander Wang," the group stated in an Instagram post. "Let's be clear: The fashion industry's lack of transparency and accountability leaves all models vulnerable to abuse, regardless of their sex or gender identity."
So far, Wang's celebrity clients, including Lady Gaga (pictured at the 2015 Met Gala), Rihanna, Doja Cat, Balla Hadid, Kylie Jenner, and Miley Cyrus, have remained silent.
Rappers who name dropped the designer in their songs include Kanye West, 2 Chainz, Lil Wayne, Quavo Huncho, and Vic Mensa.
