The Duchess of Sussex attended the opening ceremony of the One Young World Summit in London in a long-sleeved flowing purple dress by Aritzia with navy pumps. Princess Meghan left her hair in loose, casual cascading waves. The Duchess of Sussex was radiant and in a positive mood as she smiled for the cameras.

If you follow royal news, you know that Princess Meghan and Prince Harry gave a raw and honest glimpse into their personal struggles with the tabloid and overall media atmosphere in the documentary Harry and Meghan: An African Journey (opens in new tab). Tonight, however, the Duchess showed no signs of despair and focused on the summit.

The Summit has been held since 2010, and Princess Meghan has been an avid supporter of One Young World since 2014. Princess Meghan also serves as Vice President of the Queen's Commonwealth Trust, which has partnered with One Young World to invite 53 people to tonight's event. The summit will consist of speeches, panels, networking, and workshops. Focusing on what matters most has always been Princess Meghan's forte, and to channel her determined spirit, she happened to wear a look similar to that of Princess Diana circa 1996.

Princess Meghan's Power Woman purple dress is sold out, but you can find similar long-sleeve options from her beloved fashion label ahead.
