The effect is in full swing. After her earlier this week, the handbag that the former Suits star carried on her has immediately gained a lot of attention.
The future royal teamed her navy coat from Canadian brand Mackage with a bag from Edinburgh-based label Strathberry for her first royal walkabout in Nottingham on Friday. The is available in a variety of colours, but Meghan's burgundy, navy and vanilla version sold out within 11 minutes, the brand told ELLE UK.
In a statement, a Strathberry representative said the company was "thrilled" that Prince Harry's fiancée picked one of its designs. The brand has confirmed that it will be restocking the sought-after bag in the new year.
"We are delighted at the news of Meghan and Prince Harry's engagement and wish them all the best for this exciting period. It was a fantastic surprise to see that Meghan selected one of our core Strathberry styles to carry on her first royal engagement."
The independently owned label prides itself on quality craftsmanship. The bags, which start at £225, can take up to 20 hours to make and are stocked in luxury department stores around the world.
Just like with the "Kate-effect," people have been desperate to match Meghan, which has already increased sales for a number of other brands. The coat she wore to the engagement photocall sold out at Canadian label Line The Label on Monday, and her nude heels from Aquazzura also sold out on several sites.
