For official photos released several years ago, Queen Silvia of Sweden wore a deep orange/rust Jacques Zehnder ballgown with her Order of the Seraphim sash. 

Two photos were released; one featured Queen Silvia with her husband King Carl XVI Gustaf while the other was a solo shot. Both are featured in this post. 

The dress, which is long sleeved and floor length, had rose embellishments around the neck and sleeves. It also had a full and flared out skirt in true queen fashion that you see in fairytales. It featured buttons, matching the gown's color, down the left side of the front of the gown.

She accessorized with the Leuchtenberg sapphires that she has worn on many occasions, as well as the Leuchtenberg Sapphire Tiara.
