Timeless in this case means ample use of black. “It’s easy to imagine that a charcoal skirt or an ebony blouse could have been worn either in 19th-century Norway or on the streets of New York today,” Goldstein said. “The main exception to this palette is the character of young Oswald, who is in white. His flowing cardigan looks period but could also be more recent.”

Early in the Ghosts rehearsal process, Goldstein had put Lily Rabe, who plays Mrs. Alving, in a red dress; he’d outfitted her in a similar shade when he costumed a 2012 production of The Merchant of Venice, in which Rabe was Portia opposite Al Pacino’s Shylock. “This time the red didn’t quite cut it,” Goldstein confessed. “It had been a while since I’d worked in the Newhouse” -- he has done five plays there and won a Tony for a LCT staging of The Rivals, in the Beaumont -- “and I’d forgotten just how intimate the space is. You have to be careful with bright colors.”

The costumes in Ghosts are “shopped”: not built but found online or at stores. “Lily for herself likes to buy things from a place in NoHo called Maison Mayle. I’m grateful to them for their help on this Ghosts and to Lily for putting us on to them.”
