The costume designer, who memorably competed on Season 4 of the Bravo reality show, died Thursday of a heart attack. The Project Runway favorite had been in and out of the hospital over the past two years after suffering a debilitating accident in fall 2017 that left him in a medically induced coma after falling and hitting his head. Bravo's Andy Cohen paid tribute to March on Instagram by posting a picture of him dressed as Lisa Vanderpump. "He designed for everyone from Beyoncé, Gaga, Madonna, Meryl, Prince and many legendary downtown drag queens (And Sonja Morgan!)," Cohen wrote. "He had a big booming laugh; he was a joy and delight."
