About Aster & Oak's Sizing Chart:
Measurements are a guide only, some styles may be sized differently and have different measurements. For instance the Harem pants have a different waist and hip to the leggings and the girls tees are a slimmer fit than the boys tees.
Please note that all of Aster & Oaks clothes are cut generously to allow room for growth and will generally fit well beyond the recommended age. If you are still unsure about which size to choose for your child, we recommend going up a size – at least that way, they can grow into it
