JO Galvis was 15 when she got a tattoo on the centre of her lower back. She had been fighting with her family and living at a friend's house. What better way to infuriate her parents?

Ms Galvis, who is now 29 and lives in New York City, grew up in Colombia, where she just walked into a tattoo parlour in Bogotá and glanced at a sheet of paper crammed with popular design choices that hung on the wall.
