My recent obsession have been both these black bow shoes from Zara with sling back heels. They look perfect dressed up as well as dressed down. The small slit of skin between the bow and toe added with the open back give them a younger edge.
Also this COS yellow wool skirt brightens my mood. It is of very good quality and perfect in this windy weather because the wool makes it stay put (no Marilyn-esque moments). In winter it can be paired beautifully with browns, creams, greys and whites- adding sunshine to the dreariest day.
