"The Capitol is the seat of Panem's brutal, totalitarian government and is located in the northwestern Rocky Mountains of the former United States and Canada. Panem is surrounded by twelve outlying districts over which it exercises hegemony. The Capitol is the home of the dictatorial President Coriolanus Snow and several major characters."
"Style and fashion are very important to the aristocratic citizens of the Capitol. It is common for them to tattoo and dye their bodies, as well as undergo plastic surgery to alter their appearances."
The Capitol's collection was the easiest: bright-colored clothes and shoes, ruffles, fascinators, flashy stuff, etc.
