At the Saint Laurent Autumn/Winter 2014 show, mini-skirted models wore thick, black opaque tights. I think this is an ideal way to wear this Autumn's shorter skirts, especially for those who are hesitant about showing more leg.
H&M do a good selection of opaque tights and my two favourite pairs have the added benefit of being control tights, which help to give a firm, trim silhouette.
The first pair, in the photograph below, H&M 100 Den Matte Black Control Tights are very thick and matte.
