This little outfit is so versatile & can be worn almost any time of the year. It is made of 100% cotton. The top is made of soft cotton knit with long sleeves & features a dinosaur (and a half) that are appliquéd on the front & the scales even have a 3D affect (see pic #3) which is a fun touch. The top also has the stand 3 snap crotch for easier diaper changes & will stay tucked in nicely. The pants have an elastic waist & soft knit ribbing at the ankles. NWT
