The New Designer Showcase (新人デザイナーのショーケースShinjin dezainā no shōkēsu) is a fashion show event that is held every six months at Polaris Academy. The purpose of the event is for the new students in the Designer Course to be able to show off their newly created brands. The event was first held in Episode 4 of Aikatsu: Galaxy!.
Each designer (or designer's representative) must be wearing a non-Premuim Rare dress from the represented brand. Private brands may not participate. The performing idol only must be able to do the brand's special appeal. The designer must have come up with a name and basic information for the brand prior to the event. At the end of the event, the newly debuted brands will be added to the school's Brand Encyclopedia function on the school's Aikatsu Phones.
