Made of 100% cotton material. A cute item with various details such as the size of the polka dots on the sleeves and front, and the color of the collar. I think it's an item that will be a highlight whether you wear it as is or with overalls. Definitely an item you can wear for a long time until early spring. size→SMALL (GyMBOREE size chart: 1.5 to 2.5 years old) Width: 30 cm Length: 31 cm ⚠︎ Slight fading ⚠︎ As this is a used item, there may be some scratches, stains, and signs of wear.
