This is made from a very high quality, cotton spandex blend, that is lovingly called “milk silk” cause it’s so soft! This is perfect for the kids with sensitive skin or who are sensitive to fabrics. They are soft enough to sleep in! It’s designed to withstand stains and wear. They also run a little big, so you will get your money’s worth! *Solid colored pieces are generally a soft cotton knit blend, rather than the cotton spandex blend, but still a very high quality that will resist stains and wear.
