This is a 3-piece set for babies, including a top, pants, and a headband. The material is similar to a cotton T-shirt, and it feels good against the skin. The gentle colors are very cute, and I think your baby will look adorable in them. Due to my child's growth and the changing seasons, I missed the opportunity to dress them in it. I only put it on indoors for a short time to take photos. It has been washed with additive-free, gentle detergent.
