“This issue is SERIOUS,” he wrote. “It has completely taken over my life.” He acknowledged that he had lost an “EXTREME amount of weight” and said he had been “living in torment.” He said that he did not have cancer.

He was looking extremely frail in his final runway show.

ObviousMag broke the news, reporting, “American Fashion Designer, and Project Runway alum, Mychael Knight has passed away. He was 39 years old. Mychael died at 7:25 am EST outside of Atlanta, GA on October 17, 2017, surrounded by his loving family and friends. His family asks that their privacy is respected during this time of grieving.”

2. Knight’s Family Described Him as ‘Generous’ & ‘So Full of Life’

In a statement to ObviousMag, Knight’s family called his death “untimely” and said they were still processing it.

“We are still processing the untimely death of our son, brother, friend, and uncle. Mychael meant everything to us and we loved him dearly. He was generous and so full of life. This is how we choose to remember his legacy,” the Knight family wrote, according to the publication.

On Facebook, Knight’s last post was about a fashion show in September. He described himself as “Son. Brother. Uncle. Friend. Fashion Designer. A Black Man.” The Facebook page says that Knight was living in Los Angeles and was the owner of Mychael Knight, Inc.

Recent photos of him with family also show him looking very thin lately, but the posts about his health are no longer up. In August, he was urging fans to come to a fashion show and after party for it. He had also recently posted about family. On Mother’s Day, he wrote, “You are absolutely THE ONE! Celebrating you for all the love, support, & nurturing you give me and our family. #HappyMothersDay Pamela Williams-Knight! Love You To Life ✨?”

In a lengthy blog post announcing Knight’s death on ObviousMag, author Jerris Madison wrote, about meeting “Mychael in Philly almost 10 years ago. We both were booked to speak on a fashion panel for Radio One. We instantly clicked and became friends. He was a true Southern Gentleman and had no problems telling you that he was from the South. No matter what situation or industry event we attended, he always remained himself. I admired that about him. He loved his family so much and others, it reflected. He was a big Momma’s Boy, his mother was one of his best friends.”

Madison continued, “When I lost my leg due to a rare form of bone cancer, Mychael helped me get my confidence back. I once complained how designers aren’t making clothes for people like me. Mychael’s immediate response was, ‘I got you! Give me a few days to sketch something for you.’”

He was still designing almost until the end.

According to AJC, “Knight’s Spring/Summer fashion collection titled ‘Mercy & Grace’ featured colorful skirts, dresses and shorts that fans seemed to love. His designs have appeared on celebrities ranging from Sherri Shepherd to Iggy Azalea.”

He didn’t make it the first time, but in 2006, he was granted a slot on Season 3 and quickly became a fan favorite.”
