Sister figure

NUN

Think of a woman who takes vows and wears a habit in a religious order.

The clue "Sister figure" plays on the double meaning of "sister." In a religious context, a nun is often called a "sister" as part of her title, like "Sister Mary." The word "figure" hints at a person rather than a literal sibling, steering you toward the answer "nun." It’s a straightforward definition with a slight nod to common terminology in Catholic or Christian orders.
