Our children’s line fits true to size in everything. We allow extra length for shrinkage. They are meant to be snug fitting per CPSA guidelines. Milly Marie is made to the maximum measures allowed for natural fibers. If the child you are buying for is between the 30th and the 75th percentile order for their age or order a size up if you prefer a looser fit.
