Size range
3, 4, 5, 6, 7, 8, 9, 10, 11, 12 years old.
Choosing the right size for underwear or swimwear: these products must fit very close to the body (especially for stockings, panties or boxers because these are small items for which height is less important than the build and age of the child....) it is recommended not to take an age higher than the child's actual age. For example, until a child reaches 7 years old, make small items of swimwear and underwear in 6 years. If in doubt, it is better to take the size below than the size above.
