Hey ladies - I need your ideas!

We've had a last minute invite to The Grand White Dinner on Saturday night.

If you don't feel like linking to the page, it's basically a fab outdoor event with a picnic dinner, live music and magicians and flame throwers and all sorts of other awesomeness. The location is secret until just three hours before the event. The dress code is all white with a touch of green.

I think I will need to shop for this dinner... My few white items are too summery and too casual. Our autumn evenings are very chilly now, although the day time weather is still warm and the event starts at 3pm.

So... your suggestions for the ideal outfit for me to shop for?
