How to choose the right size

Every child grows at their own pace. For this reason, we recommend using the current weight and height as the main reference, with age as a complementary indication. If your child falls between two sizes, we suggest going up to the larger size, allowing more room to grow and a longer-lasting comfort.

For children between 6 and 8 years, we recommend choosing by current height and weight: typically above 122 cm, the 8Y size is preferable to 6Y (we do not currently carry the 7Y size).

The measurements shown in this chart are indicative and may vary slightly between brands and models, as each maker applies their own cutting and tailoring patterns.
