This is a set of 4 baby undershirts: 2 short undershirts and 2 combination undershirts, all made of 100% cotton. They were worn until around 2 months old, but they are in clean condition with no noticeable stains, possibly because I bought multiple undershirts and rotated them. The outer closures are buttons, and the inner closures are ties. The natural colors are adorable, and the undershirts look incredibly cute on babies. Highly recommended! ^ ^ - Quantity: Set of 4 - Colors: Cream, beige, star pattern - Material: Cotton, rib knit - Size: 50-60cm Thank you for looking.
