The Adams range of school clothing is aimed at children between the ages of four and ten. Sainsbury's Jeff & Co Essentials will target those of 11 and above. The clothes will be supplied by BMB, which makes Jeff & Co. Priced similarly to other stores' uniforms, boys' trousers will sell for about £12, and packs of two shirts will go for £7.99. Sainsbury's also plans to expand other parts of its Jeff & Co Essentials range.
