Ordered tracksuit for DS1 for school - size 11 - from Next. He is a tall 10yo (147cm+). The trouser length was fine but the waist was a total joke - about 4 inches too big and no drawstring.
But he's not thin really - kind of average I would say. And I believe Next actually do a bigger kids range too!
Who are these trousers supposed to fit? And more to the point, what is DS1 and his thnner pals (he has a number) supposed to do for joggers???
