How does John Meaney use imagery in Blonde Ambition?

Imagery:

"So often Anna - who'd traveled all over the world - felt like Los Angeles was an alien universe, where she needed a full-time cultural guide in order to understand the natives" (Chapter 8).

"Out on the dance floor a girl with choppy dark hair lifted her Bebe T-shirt to expose a pair of perfect breasts. Yawn. Like having perfect tis in Los Angeles was something special" (Chapter 18).
