1. A black sequinned Giambattista Valli Haute Couture gown for the Berlin premiere of Farewell, My Queen
2. A striped skirt over green dress look from 10 Crosby by Derek Lam for the film's photocall earlier in the day. We're loving the yellow sandals too.
3. A check jacket over a sheer black shirt and beige skirt (plus enormous bunch of flowers) at a press conference for Germany's Time Magazin.
Of all the looks we're going to say that the second is our favourite, partly because it's so enthusiastically spring-focused and we're looking out of the window and seeing snow, and partly because it shows Diane's (or her stylist's) genuine enthusiasm for playing with fashion.
