Americans and Canadians alike tend to think that all the different traditional 'Santa' figures are one and the same, and use all the names interchangeably; Santa Claus, St. Nicholas, Father Christmas, Kris Kringle - but they are not the same. They are all completely different traditional characters unique to their own countries of origin.
Russia also has their own traditional Christmas figure - Father Frost, who is a Russian fairytale character who travels throughout the land on Christmas delivering gifts with his granddaughter Snegurochka also known as the Snow Maiden.
I loved the images I'd seen of them online, and was inspired to copy the traditional snow Maiden's outfit for my Princess Elora in A Christmas Story a few years back. Then it was just a simple matter of combining parts of my Santa and St. Nicholas outfits to create Father Frost.
