Domenica Castaldo Ellison is one of Barney’s top fashion and styling consultants. (Her office there is filled with your fantasies.) Her background is full of stints with global, high-style personalities and brands: Faberge, Elizabeth Arden, Revlon, Saks Fifth Avenue, Donna Karan, Vera Wang, Michael Kors . . . leading to a client list that includes many people youâ€™ve most definitely heard of, yet she remains a true pleasure.
