My daughter is soon starting 6th form and also volunteers and is keen to find a smart looking pair of black trousers, probably reasonably fitted. Where is best to look? She is a size 6. We haven't had any luck at her usual favourite shops and I can't quite get myself to sit though dozens and dozens of trousers on M&S or H&M. Happy to spend a bit extra as I hope she will wear them for a good while.
