Thank you for viewing! This is a set of three 70-size baby undershirts. The beige and light brown ones are cotton, and the frog mesh romper is made of a thin, quick-drying, breathable fabric. You can layer a dress or overalls over them, and short-sleeved rompers are often worn underneath in the fall and winter, so why not get a great deal on this set of three? ^ ^ Feel free to message me!
