This is a pleated blouse from Droite lautreamont (a brand under Lautreamont). It comes with a waist ribbon and a sleeveless inner layer. The color is olive, and the inner layer is the same color. Originally priced around ¥19,000, the size is 2, and it has only been tried on once. The design allows you to wear it either with the ribbon tied at the waist or without the ribbon. Also, because it's made of thin fabric, the pleats can be easily maintained with a clothing steamer.
