Finding it difficult to shop on line from Next as the sizes seem to have changed, Next always seem to be a bit on the small size, so i purchased a larger size of leggings for my grandaughter, she is very tall and slim so as they are leggings and wanted the length in the leg ordered 14yrs they are very big, not particularly long but large around the waist. I bought a pair of size 6 womens yoga pants at the same time and they fit her perfectly. The leggings themselves are decent for the price but pointless if the sizes do not match people.
