Organic Baby Cotton Romper in Grey is part of Estellas unique collection of baby pants. Made in Holland, these baby rompers are made of 100% cotton and they are soft and fit great. Like all our baby rompers these imps & elfs rompers run a little small so if for example the child is 3 months old, we recommend that you purchase the 3 6 months size, NOT the 0 3 months size. Feel free to email or call us if you have any questions.
