Catherine Cottage Girls' School Entrance Ceremony Suit Sailor Collar Children's Clothing Ensemble Girls' Suit Michelle Alfred TAK Kids Catherine Cottage Elementary School This is a set-up of a plain jumper skirt and a sailor collar jacket. The color is navy blue. Fabric: The jumper skirt and jacket use the same fabric. (The navy blue is the exact same fabric, including the color.) You can wear it for various occasions, from the glamorous scenes of graduation and entrance ceremonies and recitals, to entrance exams and memorial services. It's a relatively thin fabric, perfect for spring and autumn, but you can use your own items to protect against the heat and cold, so you can use it all year round. Although it is thin, it is firm and wrinkle-resistant.
