Size Guide

Size Guide

Our baby onesies are available in sizes Newborn to 9-12 months. Sizing is a general guide only. Keep in mind that all babies grow at different rates and, like us grown-ups, have different body shapes and sizes.

Also, clothing sizes for babies differ slightly from brand to brand as there is no standard measure of baby sizing. We strongly recommend purchasing a size up to the baby's usual size/age as Dorveille sizing runs between true to size and slim.
