Marching☆Melodies is the name of the costume the 20 person idol unit L.M.B.G wears in Idolmaster Cinderella Girls. While the group has worn the costume since their debut in 2D illustrations, it did not have a name until it's release in the Starlight Stage dress shop on August 10th, 2017. The outfit was also worn in the unit's Starlight Stage debut song, Hi-Fi☆Days.
