However, Kate, Duchess of Cambridge, failed to make the list at all. The conclusions were released by online fashion platform Lyst in part of a public report in Fashion.
It was based on a study of searches conducted by more than 100 million shoppers around the world.
Using the data, Lyst identified what she said were the 12 most iconic fashion moments of the year.
They included the Duke and Duchess of Sussex, who stepped down from their royal duties on the front lines at the end of March, and Princess Beatrice married in July.
Meghan and Harry shocked the world in January when they announced their intention to step down from their position as prominent members of the royal family.
Instead, the couple pledged to become “financially independent” and said they would split their time between North America and the United Kingdom.
However, a number of the outfits that Megan wore in her recent royal engagements in March have become a fashion buzz.
On March 5, the Duchess wore a gorgeous blue Victoria Beckham dress to the Endeavor Awards at the Mansion House, London.
The event celebrated current and former members of the armed forces who have used sport to recover from injury or adjust to post-military life.

The annual event, attended by senior members of the royal family including the Queen, is held to celebrate the global role played by the Commonwealth.
For the occasion, Megan wore a gorgeous green dress by designer Emilia Wickstead.
Searches for the designer rose 286% in the aftermath of the event.
The other Queen who presented one of the best fashion moments of 2020 was Beatrice, as a result of her wedding on July 17 to Eduardo Mapelli Mozzi.
The event, already delayed due to the coronavirus, was held in Windsor in front of a small group of guests.
Among the attendees was the Queen and Duke of Edinburgh.
After the service a reception was held at Buckingham Gardens.
Beatrice wore a vintage wedding dress for the occasion that she borrowed from the Queen.
Over the next 48 hours, searches for “classic wedding dress” rose 297 percent.
Later in the day, Beatrice described it as “a lot of fun”.
