And luckily, they're not hard to wear either. Here are my thoughts:
You can wear them with virtually any top - although they work best with pretty blouses.
They look better on curvy figures - why should the beanpoles always have all the fun?
I don't care how long your legs are, pencil skirts do not work with flats.
I love them high waisted and cinched with a big belt.
You should get extra style points if they're in a bold colour, like the cobalt skirt from Wallis.
Here are my fave five:
