Diane Kruger in Giambattista Valli and Derek Lam in Berlin

I am a huge admirer of Diane Kruger's style. I even overlook the fact that she has ensnared my husband, Pacey Witter, and is living happily ever after with him, simply because she is one of the most successfully adventurous actresses around. She is always on trend - but in that way that is slightly twisted and just before everyone else. She is always beautiful - it's just the way she was made.

And yesterday, as she opened the 2012 Berlin Film Festival, she continued to look wonderful, unexpected, glossy and bright. First in Derek Lam stripes and prints, and then later the evening in a gloriously surprising polka dot Giambattista Valli black gown. Stunning.
