Cards

The Aikatsu Cards are used by students of idol-producing schools such as Star Harmony Academy and other idols to dress up their appearance. There are also brands, each with it's own top designers whom works to design dresses for the Aikatsu Cards. The cards contain digitized clothes which are worn by idols during performances and auditions. The clothes come from various types of brands and have varying degrees of rarity. Although most clothes come in specific coordination, players are also able to mix and match different cards to find a good combination.

They are divided into four categories: Tops, Bottoms, Shoes and Accessories, with some cards, such as one piece dresses, eliminating the need for others.
