How do I select/change/add my size?

Size selection is chosen at checkout when placing your initial order. After your size has been chosen at checkout we are unable to accommodate size changes due to inventory. We apologize for the inconvenience! For future Jilly Boxes you will be notified when it is time to update your size! You can make any changes to your membership in your Jilly Box account at least 30 days before the next billing date.
