A Dress Change (ドレスチェンジ) is an event that occurs during Dressia Chances in a battle stage. Dress Changes are determined by accumulating Dressia Gauges, which will be combined with the Dressia's level and skills to determine the winner and grant them the power to change its dress. The idol before the battle stage must summon 2 or more Dressias to make a Dress Change occur.
