Ellery’s debut comes seven months after he was first asked to walk in Simons’ show.

The designer requested the teenager to model in his February 2018 show but his musician father had voted against it.

“He originally asked me to walk. But my dad had different opinions,” Ellery toldWomen’s Wear Dailyat the time.

“Ellery has a great love of Raf,” added Dern, who attended the show with her eldest child.
