Our size charts indicate which clothing best suits your body proportions. This is just a guide and products very depending on style and tolerance (all clothing is made "within" a set of measurements). If you don't know which size will fit you - the best thing is to measure both your chest and waist. For children, height can also be important. If you are close to the top end of a size, we always recommend going up to the next size. For example if you measure your daughter or son to be 140cm high, then we recommend you order the 2XS (152) size. Please note that items that have been personalised with an initial or number CANNOT be returned.
