"I spent as much time as I could alone in our room, trying to empty my mind of every thought, to forget where I was, even who I was. […] I decided to put on his clothes. […] This gave me such intense relief […]. I would never stumble through the confusions of my own character again" (5.4-5).
This quote is directly from that piece of literature, showing that putting his clothes on instead of hers relaxes her.
