The skirt Molly sits comfortably around the waist, and you can adjust the tightness with the waist string. Choose a size based on your child’s height. For example, if the child is 98 cm tall, choose the size 98. If the child is between sizes, choose the larger size.
If you know that the child is slim you can size down 1-2 sizes on the width of the skirt, otherwise the waist can become a bit bulky with too much fabric.
