I'm definitely one for keeping staple pieces in my wardrobe for a long time regardless of whether it was 'last season'. I think things like the below will see you through so many years and all seasons. I love this in the winer with some thick tights, boots and a jumper, but also in the summer as styled below. Whatever the weather black will always be my 'go-to'.
I love the little floral print on the skirt and the zip fastening down the front for detail and actual purpose. It also has pockets for those days you want to be super cool. I picked up these shoes after desperately needing some smart/casual black flats. I haven't quite mastered how to walk in them yet - I know how you must be thinking right now. But I find them every difficult and I almost stomp when I walk in them. How ladylike...
(I thought I would add this little number in here as it pretty much sums me up; pigeon toed, bum out. It made me laugh at least)
