Below you will find the body measurements that we use. Most of our product is available in single sizes, this means the sizes increase at an interval of 1 year i.e 7-8, 8-9, 9-10, 10-11 and so on. If you are buying jumpers and cardigans please use the dual size table. This means the sizes increase at intervals of 2 years in the older sizes. i.e 9-10, 11 -12, 13 – 14. If you are buying trousers or blazers, the size guide states length of the product, not the body measurement.
