Costume
Inspired by Marching Bands, their first original costume consisted of a white top and skirt for three members, while Kaoru wore pants and Hagumi chose black pumpkin pants. A red vest with gold and black detail is worn over this with three chains attached at the middle. The black and gold collar accents the fringed shoulder-pads, wrist accessories, thigh-length boots, and marching hats.

Their second band uniforms have been inspired by the Circus, with a red, white, and black top with gold detail and five pom-poms sewn down the center, coming in the band members colors. Sticking out of the bottom from this is ruffled, layered light blue and white fabric with the same pom-poms in various sizes, worn with a pair of black short-shorts. While Hagumi and Kokoro have black shoulder straps and ruffled sleeves beneath the shoulder, Kanon wears a white blouse with her dress. They also have a polka-dot bow on their neck and blue earrings. Kaoru and Michelle wear a male variant of this outfit, including a jacket and pants. Each member wears the same black, white, and red shoes with curved heel and pom-poms sewn to the toe in her own color, along with a black and gold top hat with Hello Happy World! and a smiley face drawn on it, and a red ribbon wrapped around the middle.
