This is a formal set from Catherine Cottage. My younger child wore it for my older child's entrance ceremony and Shichi-Go-San (a traditional Japanese festival for children). It's a set with an authentic design and thoughtful details that make it easy for small children to wear, and it received very good reviews from those around us ^_^ Shirt Length: Approximately 41cm Width: Approximately 33cm Pants Waist width (maximum): Approximately 22cm, with adjuster Inseam: Approximately 23cm Shipping will use recycled materials.
