When looking to dress up a knitted jumper but aiming to keep things understated at the same time, pairing it back with a black leather skirt is an excellent idea. I wear my leather skirts year round, opting to pair them with a simple black cami in warmer months and switching to a wool knit such as this one from Morrison in the cooler months.
As a fan of the high collar, this knit caught my eye, but I think it is the asymmetrical hemline detail which gave it a little something extra. Given its length, I opted for the longer skirt, all aiming to create a long silhouette. I know the ankle boot creates something a little blocky (which I personally like) but a strappy black heel would work too. I could re-wear this look again and again all Winter and probably will.
