Sociologist and author Sarah Thornton hadn't really given too much thought to her breasts for most of her life. But in 2018, after undergoing a preventative double mastectomy and reconstructive surgery, she began to consider the social and cultural significance of them.
Thornton's latest book Tits Up investigates the fixation with mammary glands, drawing on insights from sex workers, milk bankers, plastic surgeons, witches, and bra designers.
