In a soft-furnished clinic within Melbourne’s Royal Women’s Hospital, a revival is under way for the first things most of us put in our mouths. Here, nipples are being made anew. “We do around 10 a fortnight,” says tattoo artist Jenny Langdon. A neat blonde woman whose own skin is devoid of ink, Langdon works most days as a plastics clinical nurse consultant next door at the Royal Melbourne, but on Thursdays she works at Australia’s first nurse-led nipple tattoo clinic.
