What physical trait does she receive complements about from the two men that had some sexual involvement with her?

Sophie Treadwell's play Machinal is based on the real story of a woman named Ruth Snyder, who murdered her husband in the year 1927. Snyder went to trial and was sentenced to death by electric chair.
In the play, the main character, Helen, usually referred to as the Young Woman, marries a man she works for, despite the fact that she finds the thought of him touching her suffocating and repulsive. Not long after getting married and having a child, she meets another man who seems to be a stranger to the stifling world she lives in, and she spends the night with him.
Both men compliment the Young Woman on her "pretty little hands." In fact, when she goes home from work and tells her mother that Mr. J wants to marry her, she tells her mother, "He says he fell in love with my hands."
