W. Wysocki Kieff was the Official photographer to the Russian Imperial Court. Members of the court, courtiers, retainers and servants were often times photographed at this studio. The honor is very similar to royal warrants in England, where shops can display a sign stating that they provide the British Royals with shoes, soap, umbrellas, silver, cars, etc....
I believe the studio was in St. Petersburg. The style of her clothes would suggest 1880's or 1890's.
Here is a site with other photos of W. Wysocki Kieff.
