Gatsby takes Daisy to his house to show off his wealth and material items in hopes she will marry him.
Daisy suddenly begins to cry as Gatsby throws many of his expensive shirts to her
I'm so sad because...I have never seen such beautiful shirts before
Daisy was not simply crying over shirts like she said she was. She was crying because she was overwhelmed by all of the confusing emotions she felt. She has feelings of regret for leaving Gatsby since she still has love for him and he is now wealthy. But she also does not want to leave her marriage and child with Tom.
Daisy faces the man vs self conflict as she has to make the tough decision of choosing between Tom and Gatsby
