Can be used for a long time by converting it into a dress shape as the child grows. It becomes a coverall when you fasten the snap buttons in the crotch area (prevents riding up). With sleeves to protect the shoulders from the cold. There is some pilling, but no noticeable stains. [Size] Can be worn from newborn to around 3 years old (including when worn as a vest) [Color/Pattern] Off-white, sheep pattern #Babysleeper #BabyPajamas
