Thank you for looking. Kindergarten Smock for School Preparation This smock is made for kindergarteners. It is made of 100% cotton fabric. We use domestically produced fabric. Body: 100% Cotton, Lightweight Sleeves: 100% Cotton, Lightweight We believe this fabric can be used throughout the year. All fabrics were hand-washed once with Emal detergent before cutting. A loop has been attached for hanging. The elastic is slightly longer to allow for adjustment. Please adjust it to your child's size after arrival. Size: 100-110cm Width: Measured from right to left, under both armpits Approximately 44cm Length: Measured from the top to the bottom of the back panel Approximately 43cm Please compare with clothes you already own. For reference... My second son was small for his age (at the front of his grade). He used the same size smock for two years. Nensho (age 3-4): Baggy. Nenchu (age 4-5): Perfect fit. Nencho (age 5-6): The sleeves became short, so I made a size up. Smock Smock School Entry School Entrance Preparation Kindergarten Nursery School School Entry Goods Handmade
