My youngest grand daughter is also going to High School in September but she won't be fitted for uniform till late in the Summer holidays she grows so quickly especially in the foot dept. She is also tall but skinny with it we don't usually have too much problem fitting her but she opts for trousers rather than skirts for the Winter months. Her Mum usually buys her clothes in Sainsbury, Next and M & S.. good luck
