I think that the ideal uniform for a schoolboy is the following: dark blue or black jeans with a shirt. No tie. I think that jeans are more comfortable, than the trouses. The colour of the shirt should be light or dark blue. White shirts should be worn only on special occasions. A waistcoat is compulsory in autumn and in winter. The waistcoat should be black.
