text: New Pretties When an Ugly turns 16 they undergo a massive Operation that makes them perfect in beauty and health. The Operation completely overhauls a person's body structure and also includes lesions upon the brain, which makes them compliant and less likely to cause conflict. The lesions also tend to "dumb them up." They become New Pretties and are moved into apartments or mansions in New Pretty Town. New Pretties do not have to work; the only thing they do in New Pretty Town is have fun and maintain an active social life.
  New Pretties generally join popular cliques, such as the Swarm (who only go places massed into large groups), the Hot Airs (whose favored pastime is floating in hot air balloons), and the Crims. The Crims commonly consist of those who pulled the most tricks when they were Uglies, and are therefore considered to have a 'criminal' past, hence the name.
  Middle Pretties
  Middle Pretties have picked their professions and gone through a second, minor operation that makes them look older and wiser, but still beautiful. They then move to the suburbs and are allowed to marry and have children, but are encouraged to do so only every 10 years, so as to discourage the formation of sibling bonds, and to ensure that the population of the city doesn't rise over capacity. Middle pretties are the working class. The Middle Pretties' Littlies (children) are allowed to stay with their parents until they turn 12.
