While their appeal might not be as obvious as the ankle variety, knee-highs deserve just as much space in your boot collection. An outfit transformer, they turn almost-autumnal pieces into true seasonal heroes; team with lighter-weight dresses and skirts, adding knitwear as temperatures drop. During winter months, use to add polish to knitted separates or slip under a cocktail dress in lieu of tights. Heeled iterations make for a sophisticated silhouette, but ensure the height is walkable. Classic black, tan and burgundy will remain timeless, as will animal print.
