This is a cable knit sweater from Baby Gap. The size is 18-24 months. It's for ages 1.5 to 2 years old, but it runs quite large and can fit up to about 4 years old. I think the size is around 90-100. It's off-white and looks very mature and cute. I also have a slightly smaller size available. Perfect for matching outfits with siblings. This is a series that comes out every year from Gap, and the design changes slightly depending on the year, but this one is made of a soft cotton material and doesn't have elbow patches.
