In 1979 de Castelbajac married fashion journalist and model Katherine Lee Chambers. They had two sons but the marriage ended in divorce.
The designer is currently engaged to actress Mareva Galanter.
In the '80s, a lifelong fascination with graffiti inspired his work with Jean-Michel Basquiat, leading to the creation of their show stealing gown in 1984.
