I have an 8 yr (9 in may), who is aslready 143cm tall, she gets most of her clothes from the boys department (she is a tom boy) or supre and places like that. The other place is best and less have good clothes that are cheapish and last ages.

I think there is a gap in the market for normal clothes around size 8-12 for young girls who a taller then average for their age. Hence why I end up at supre, tempt etc, I have found some good plain tops or ones with small pictures there and also leggins that fit well.
