Mrs. Claus

The wife of Santa Claus in many stories. She's often portrayed as a kind, elderly matron who helps her husband and the elves in various ways, whether it's cooking delicious meals, or even helping supervise the toy factory.

Her origins are as varied as those of her husband, but regardless of how she begins, she usually ends up as a Granny Classic.

Her outfit is typically a red and white version of the classic granny dress. Sometimes the red is replaced with green, to complement her husband's outfit, and complete the Christmas theme. Rarely will she ever wear a "Happy Holidays" Dress, and especially not a Sexy Santa Dress (unless she is crossed with Grandma, What Massive Hotness You Have!). Still, ladies who are merely dressing as Mrs. Claus will often wear those dresses when paired with a guy dressed as Santa, especially a Mall Santa.

Compare Cool Old Lady, Fairy Godmother.
