Quite short jackets look best with such skirts (only to the hips) and matching or extra long coats, a little longer than the skirt. If you don't have any of them, you can wear thick, but a blazer fitted at the waist or a jacket that is not too long and not too wide. But you have to remember, that such an outfit does not make the figure slimmer. A long skirt can also be worn with complete sports clothes, like for example. thick sweater with quilted fabric, down vest.
