CLOTHING SIZES

As a general guide, our clothing is designed to fit the age of the average child, for example a 2Y dress would fit age 2-3 years. If the child is over the half way point in between sizes, we would recommend choosing the next size.

There are a couple of occasions where something may have a different fit, however we always include this in the Care, Composition & Fit section of each individual product description.

For exact measurements of any item, please email us at hello@fifiandfinn.co.uk and we will send these over.
