This is a four-piece set from ZARA, including a white shirt, a vest and pants set, and a bow tie. It was worn for a graduation ceremony and an entrance ceremony and has been stored since. Size 9, 134 cm (ZARA tends to run small, so I've listed it as 120 just in case) The shirt is cotton, and as you can see in the fifth photo, one thread is a different color, but I don't remember replacing it, so I think it's part of the original design. The vest and pants are made of jersey material, and the vest's tag has been cut off. The pockets are decorative and not real. The front of the vest is navy blue, but the back has a thin checkered pattern that matches the pants. The pants have an elastic waistband. The bow tie is adjustable in length and can be worn by adults, making it the most versatile item in this set.
