I have a tall (and NOT a mumsnet willowy...) 11 year old. I'm trying to look at uniform/clothes for autumn and looking at 12-13 and 13-14 which got me wondering - at what point do they overlap with adults sizes? She has hips/tum/developing so shape wise would fill an adult shape but isnt adult height yet.
Presumably small adults can buy 9lder teen clothes?!
