Thank you for viewing! This is a popular series featuring working vehicles, perfect for boys. Consider using it to prevent soiling at kindergarten, nursery school, or extracurricular activities. The main body is made of oxford fabric, and the sleeves are made of sheeting. This allows for good arm movement. Size: 100cm (Measurements taken with the garment laid flat: Length from the back neckline to the hem is approximately 42cm, sleeve length from the underarm to the cuff is 27cm, from the neckline to the cuff is 41cm, and the width is 42cm, measured under the sleeves). The elastic in the neck and wrists has openings for length adjustment and replacement. Two are included. Made with an industrial sewing machine and a serger. I make every effort to be careful, but this is a handmade item by an amateur, so please understand before purchasing.
