Well, this isn't really so much a season basic, more a wardrobe basic, but funnily enough before I bought this, I didn't have a black skirt in my wardrobe (only a work one-that doesn't count!!)
So, I spied this black pencil skirt which judging by the style, you would not think is by good old Marks & Spencer. It has a great stretch to it, giving it a good fit, but it was the zipper detailing that really sold it to me. This was from the British Heart Foundation charity shop for £3.99.
I'm sure this will be a very versatile piece in my wardrobe and I'll wear it this winter with opaques, heeled boots, a woollen jumper and one of my biker jackets.
