CA Style A (CAスタイル A CA Sutairu A?) is a Cool Element DLC module for Hatsune Miku that appears in Hatsune Miku: Project DIVA X. This module is a collaboration with the Japanese municipal airline known as AIRDO, as this outfit resembles a flight attendant.
This module can only be obtained via Japanese physical first-print copies of Project DIVA X which includes the serial number to unlock the module via the PlayStation Network. It is free to download in other versions.
The outfit resembles a flight attendant uniform, bearing a black jacket, white shirt with a necktie and a matching skirt, black stockings and high heels. It also includes a shorter, more natural hairstyle for Hatsune Miku.
