How does Curley's wife appear in death in contrast to her appearance when alive?

The quote goes as follows,

"She was very pretty and simple, and her face was sweet and young. Now her rouged cheeks and her reddened lips made her seem alive and sleeping very lightly. The curls, tiny little sausages, were spread on the hay behind her head, and her lips were parted. "

There is a sense of calm respite in her face. The is the irony of Curley's wife being released from her torment through her murder.

"And the meanness and the plannings and the discontent and the ache for attention were all gone from her face."
