NWT, never worn. I bought many bodysuits for my daughter, but she prefers wearing 2 pieces at this age. Size: 18-24 months Materials: 100% organic cotton PLEASE NOTE: because it is made of unbleached organic cotton, thus it has some tiny cotton seeds on the fabric, they are not stain or something harmful.
