"I would say that augmentation reached a peak in 2007 — there is a sense that the really big boobs look old-fashioned."

"Augmentation also skews more working class nowadays — actually, I would say conspicuous boob jobs skew working class. In one study, a segment of British working class women, for example, see fake tits as a form of consumption that gives them status and signals that they are independent women in command of the male gaze. And then similarly, a contingent of Brazilian women who began their lives in poverty want people to know they have implants as a form of financial accomplishment...."

Said Sarah Thornton, quoted in "Why Are We Obsessed With Breasts? After her own mastectomy, sociologist Sarah Thornton sought to answer the question" (NYT).

Thornton's book is called "Tits Up: What Sex Workers, Milk Bankers, Plastic Surgeons, Bra Designers, and Witches Tell Us About Breasts."

Her mastectomy — which was done as a precaution against a hereditary form of breast cancer — included breast implants — large ones that she later had replaced with smaller ones.
