Today, Crown Princess Mary attended the unveiling of this year’s Christmas Stamp in Copenhagen as Patron of the Christmas Stamp Foundation.

The special Christmas stamp is unveiled each year since 1904 and aims to raise money for children in Denmark's five Christmas Stamp Homes.

In these homes, 1,000 children can stay each year and receive help to fight loneliness, bullying, and social isolation.

Crown Princess Mary wore a repeated white tweed coat with a black dress. She paired the outfit with her Dulong earrings, Gianvito Rossi black pumps, and a Diane von Furstenberg black clutch.
