Royal Outfit of the Day: August 15

Here's a dress worn (reworn, actually) by Crown Princess Mary earlier this year, but we didn't really have a chance to discuss it in depth at the time. It's an interesting one - interesting in a good way, I think, but you be the judge.
The dress was first worn to the Dutch inauguration in 2013 (shown above), and then repeated at a government dinner in 2014.
Covered in scattered leaves and petals, the Japanese-inspired dress was designed by Charlotte Lynggaard as part of a collection presented to celebrate the 50th anniversary of jewelry company Ole Lynggaard Copenhagen in 2013. Mary wears a lot of Ole Lynggaard pieces, so it's no surprise she was first on the list for their foray into clothing.
Interesting, right? Particularly as a choice for a royal event entailing a sash (which cuts right through the waist detail) and some sort of head accessory (a wee hat, above, and a tiara for the second appearance, below). The dress is the sort of thing that suffers when too much is added in the accessory department, and I have serious qualms about the sash issue, but I'm sort of in love with the way it moves:

So how would you style this number? Me, I'm hoping to see it again at a black tie tiara event (let's just dispense with the sash) and with the Midnight Tiara in place. (The Midnight collection was also designed by Charlotte Lynggaard, making it a good match on multiple levels.)
