Hello All, my DS is 13 years old 4"11 and 35 inch waist, which I know is quite big for his age and height but I can't find school pants which fit him, he currently wears a size 12-13 which are visibly too tight for him as you can see the strain on the button and the halfway- up zip. I currently get his pants from M&S and sometimes Sainsburys, does anybody know a good place for larger children's uniform ?
