How does Edward P. Jones use imagery in Lost in the City: Stories?

Imagery:

I am wearing a checkered-like blue-and-green cotton dress, and scattered about these colors are bits of yellow and white and brown.

Whenever I turn my head quickly, my nose fills with the faint smell of Dixie Peach hair grease. The smell is somehow a soothing one now and I will reach for it time and time again before the morning ends. All the plaits, each with a blue barrette near the tip and each twisted into an uncommon sturdiness, will last until I go to bed that night, something that has never happened before. My stomach is full of milk and oatmeal sweetened with brown sugar. Like everything else I have on, my pale green slip and underwear are new, the underwear having come three to a plastic package with a little girl on the front who appears to be dancing. Behind my ears, my mother, to stop my whining, has dabbed the stingiest bit of her gardenia perfume, the last present my father gave her before he disappeared into memory. Because I cannot smell it, I have only her word that the perfume is there. I am also wearing yellow socks trimmed with thin lines of black and white around the tops. My shoes are my greatest joy, black patent-leather miracles, and when one is nicked at the toe later that morning in class, my heart will break."
