Well, trousers cover legs as do maxi skirts and maxi dresses. I am not very tall, and have yet to figure out how to wear a maxi anywhere but the beach.
Not sure why you need to cover your legs. If it is religious in nature, I would stick with the maxis and trousers.
Otherwise, I would work with your body rather than against it. Check out Angie's guide on dressing body shapes.
I am a chubby pretty pear with ghost white legs. I still wear knee length skirts and dresses all the time because I like how they look on me. Nope, no nylons or stockings. I refuse to be ashamed of the skin I was born with. Pale is pretty too.
