Jane Fonda has one staple in her nighttime wardrobe. "A flannel nightgown - because I'm single," Fonda, 87, quipped to The Times on Saturday, July 19. "I never wore them when I was with a man." While a flannel nightgown is an essential, Fonda - who was most recently linked to record producer Richard Perry from 2009 to 2017 - noted that a different item of clothing is her most "treasured." "Yoga pants, because they are easy to put on and take off and they're comfortable," she told the outlet.
