Pajamas are beautiful, up really liked there more cotton, the bottom is more synthetics, the material is similar to leggings. In principle, the child's overalls would be better from another material to sew, let's say as up. I took for 1 year the size of 18 months (with a margin), the size at the time, i hope the winter will not become small. The child for 9 years is just the size, height 140. And for myself ordered the largest size on guess, the size approached. Well, in general, the order was satisfied.
