I have to buy some black trousers as I'm now required to wear them for work. I'm shit at office wear... So far have purchased a pair of m&s wide legged slacks that look and are awful (baggy knees). They need to be slim fitting but not tight, long enough (I'm 5'8" size 8 no bum to speak of), not dig in and not bag at the knees or bum. Budget up to £60. Thanks all.
