     The drunken women is a direct reference to Daisy the night before her wedding.  She had the first drinks of her life the night before her wedding.  This part of the story is very significant because while she was drunk, didn't want to get married, which actually might have been what she was really thinking and came out because she was drunk.  Although the scene is short it might be considered a look into her inner mind, which showed that she wanted to marry Gatsby instead of Tom, and she might have been realizing that she was making a mistake.  The author could have used being drunk as a symbol of being able to understand what she really thought without being in her head.  The reference to the drunken women has almost no significance except to this part of the story.
