New Pretty Town is the home of all New Pretties.
After Uglies undergo the Operation, they move away from Uglyville and into New Pretty Town. Almost every Ugly impatiently dreams of living in New Pretty Town's opulent mansions and can't wait to turn Pretty so they can attend its constant, incredible parties and watch its nightly fireworks displays from their very own luxury apartments.
These apartments are equipped with a "hole in the wall" that uses raw materials to create almost anything a Pretty can ask for, as long as the object isn't too complicated or too big. Once the Pretty is finished or bored with whatever they asked for, they just pop it back into the hole in the wall where it is recycled back into raw materials.
At least in Tally's City, many buildings in New Pretty Town are named after historical figures noted for their beauty and are designed exclusively for entertainment, such as the floating ice rink above Nefertiti Stadium. In addition to these locations, there is always a party going on somewhere every night where Pretties can show off their fancy clothes, drink, dance, and have fun strapping on a bungee jacket and flinging themselves harmlessly off the roof.
In short, New Pretty Town is designed to make Uglies impatient to undergo the Operation so that they may finally join the fun.
