Has anyone got ideas where I can get wooly tights for my 15yo DD who is somewhere between size 12 and 14. Ideally they will be suitable for school as well (plain black/navy/grey), but she also likes wearing skirts with casual clothes. Last year she had the largest wool tights from the M&S schoolwear range and they are now too small, and she finds black nylon quite cold when temps get down to 0 (as they are starting to).
(before anyone asks, yes she can wear trousers to school if she wants but she prefers skirts)
