Sorry, cosplayers, if you’re looking for where to buy Leonardo DiCaprio’s dad robe from “One Battle After Another,” you’re going to have a hard time finding it. The film’s costume designer, Colleen Atwood, confirms it was made from old fabric. “I found some vintage-looking fabric and made the multiples I needed for the robe,” she tells Variety. But Atwood says, “I don’t know if it’s Paul or Leo who said, ‘What if he’s just in his robe? '” And so Bob, recalling Jeff Bridges’ dazed character in “The Big Lebowski,” spends a good chunk of the movie in his robe.
