A Russian court dress:
a robe à la turque of striped silk (white for the petticoat, sleeves and stomacher) and yellow for the manteau. Decorated with fringe.
I still have no belt because I don't have enough fabric...
The dress is made according the style ordered by Empress Catherine the Great of Russia in the 1780's.
