I am looking for a pic; i don't have it so i'll try to describe it.
There are Olga and Tatiana with their mother; the girls are young, quite little girls. They both wear a very elegant light coat, whose decolltèe have dark lines; they have fashion hat coordinated with the coat and elegant boots.. The girl and Alexandra are at the top of a staircase, outdoor (don't know where, maybe the Winter palace?)
If you have it, can you post it? Thanks you so much!
