DD is currently 8 and is about average size except she is a bit taller than average. This is going to give as a few problems when restocking her uniform for next year, especially with the skirts which are generally too short anyway (except the M&S box pleat which I would like a change from) and trousers which invariably are too wide or too short.
Has anyone else had similar problems and can you suggest certain shops/styles?
You could try proper uniform shops, as DD1 has to wear a specific style of skirt and they come in a variety of lengths as well as waist sizes (they are very good quality too). I have just always gone with cheap supermarket ones, elasticated waists and one with an adjustable waist, not sure who from.
