I enjoyed looking at her. She was a slender, small-breasted girl, with an erect carriage which she accentuated by throwing her body backward at the shoulders like a young cadet. Her gray sun-strained eyes looked back at me with polite reciprocal curiosity out of a wan, charming discontented face. It occurred to me now that I had seen her, or a picture of her, somewhere before.
– F. Scott Fitzgerald
The Great Gatsby, Chapter 1, Nick eyes Jordan Baker, a professional golfer of some fame. We see his immediate physical attraction to her so it comes as no surprise that he becomes romantically involved. But in keeping with the valley of ashes theme, Jordan’s gray eyes suggest something hidden about this woman who cheats at golf and also bends the truth.
