If you dry clothes outside, always peg trousers by the leg, not the waistband. Line them up so that the seams are as neat as you can get them and use as many pegs as it takes - I find 2 for each leg is usually enough. The weight of the waistband will pull out most of the creases as the trousers dry - even linen ones (and I'm never buying those again, believe me !!!)
