This look resembles the pussy willows (I love the enliglish name for it). In sweden it's called videung. It's the grey, fuzzy catkins that grows out of a willow tree, even when everything else still seems dead.
The dress is a real ballet dress, made for a show. My sixteen year heart fell in love with it when I stept inside a dance boutique some years ago. I had to buy it, and it's still a lover of mine.
