IA/VT Colorful/Costumes

Costumes can be used in real-time songs by selecting a song marked with the "costumes" banner in Free Play and then selecting the option to the left of the start option. The Official (オフィシャル) costume, IA's default outfit, is the only one unlocked from the start. Different colors of the same costume are identified by roman numerals, although they must be unlocked separately from the original.
