Sometimes they can still shock you. Allison Williams has always been honest about how hard she works at getting her style just right. Despite this, it has actually evolved over the past few years and she really has nailed that Park Avenue Preppy Princess in Oscar de la Renta vibe. And then she goes and mixes it up with SEXY here.

I love that. I love to be surprised. I love to see something that shouldn't work, actually really work. It's a bit like last year when Olivia Palermo wore Roberto Cavalli leopard print. It really, really shouldn't have been the success it was. Anyhoodle. This is Dolce + Gabbana white lace with a giant dollop of the sexy thrown in to make us sit up and take notice. Well played Williams, well played.
