Marie and Anastasia's dresses in these have something of a kimono look, a fashion and cultural trend of oriental style, especially Japanese, popular in that era in many parts of the world, especially France. But aparently inRussian high society as well, inspite of the not-so-distant war between the two countries.
It look s great on both , maybe more so on Marie, but with a feminizing effect on Anastasia too,as young as she was.
