Now I know the truth

I caught the amazing video for Ellie Goulding's 'Anything Can Happen' recently (I know, I know, I'm so out of the loop). She wears two looks in the video, one of them being a fantastical, grecian draped gown.

I don't know if it would be possible to create a close approximation of this look as there's lots of volume and fluid draping, but it was so beautiful and inspirational, I thought I'd have a go at interpreting it, just for fun.
