This is a 3-piece set consisting of a jacket, skirt, and dress. The suit is silver gray with a slight sheen, and the dress is a glossy black. All items are size 11, L (Japanese sizes). (I think they are a bit slim-fitting.) Jacket length: 48cm Skirt length: 55cm Dress length: 90cm, which covers the knees. Used for one season, once each for a graduation ceremony and an entrance ceremony.
