Just bought dd 2 pairs from M&S, she's starting 2ndary in September, but will be wearing black trousers just as in primary. We carefully picked proper girls trousers in a more grown up style (she's mostly chosen 'boy' styles before) - but realised later that they don't have pockets. This is a Big Problem apparantly as she has discovered in her transition days that it is the done thing to abandon one's bag in the corridor at secondary during lunchtime and No-one carries it around with them 
So, does anyone's dd have trousers that have good large side pockets to fit a tissue, library card, dinner money, a collection of key-rings and some strange mouldering random items?
