No. If you create customisations in a size suitable for adults garments, which are then also assigned to childrens' garments, we will automatically resize your designs so they are suitable for smaller garments.
We have standard sizes which are used for all childrens' garments under 9 years old. Sizes 9 years and above are treated as adult sizes. If you require specific sizes for each child size, then you would need to upload each as a separate customisation and pay each origination charge.
