While Prince Harry and Meghan Markle avoided inviting politicians and foreign royals to their wedding on Saturday—Barack and Michelle Obama were noticeably absent—the couple made an exception for one pair of royals: Prince Seeiso of Lesotho and his wife Princess Mabereng.

The two were amongst the 600 guests present for Saturday's festivities at Windsor Castle. Princess Mabereng donned colorful traditional attire for the ceremony, and stood out in the best way possible.

Prince Harry and Prince Seesio, who is the younger brother of the king of Lesotho, have been friends and collaborators for over a decade, reports Town and Country Magazine. The two founded a charity together in 2006, Sentebale, which aims to provide support for HIV positive children in Botswana and Lesotho. The charity was established to honor their late mothers, Princess Diana and Queen 'Mamohato, who were both dedicated to working with HIV and AIDS charities.

The Basotho and British royals have a long-standing bond, Prince Seesio and Princess Mabereng were also in attendance for Prince Williams' marriage to Kate Middleton in 2011, as seen in the photo above.
