Light colors and loose layers do not have to be for summer only. I like the idea of dressing in layers of draping blouses, dresses, vests, knits and silk trousers around the darkest time of the year too.
For evenings, I prefer anything silky in cream or black. That is so to-the-point, just calm and beautiful, no matter what the lighting is.
And on my feet, on parties as well as gatherings at home: suede slippers.
