All measurements are taken with garments lying flat.

Length: Measure from the point where the shoulder seam meets the neckline ribbing, straight down to the bottom of the shirt.
Children's Tees
Our children's t-shirts are a standard fit. If your child prefers loose-fitting shirts, we recommend choosing the next size up.
