Often times shows will recycle their wardrobe within the show. Jennifer Aniston’s character Rachel Green wore this robe in the pilot episode of Friends in 1994. The next year, Courteney Cox’s character Monica Geller wore it in the episode The One with the Fake Monica. The usage of the robe on these two characters was likely intentional, as Monica and Rachel were known to share clothes. However, the robe seems to have been used again, likely just for the sake of convenience, on Jane Sibbet as Carol in 2007, in the episode The One Without the Ski Trip.
