At the tail end of last week I showed you the power of the Calvin Klein. The designer Francisco Costa pulls in a power-rich front row for his shows. And it now seems, for his after parties too. Turning up in bold, bright, solid colour were two of his most devoted clients, Diane Kruger and Emma Stone.

While Diane (yes, her again) wore a split yellow dress and looked fine, for me Emma stole the event in a cool snakey green jumpsuit and heels that looked risky, streamlined and perfectly fashion. Which did you prefer? Let me know.
