Meghan Markle's Meghan Effect is in full swing again.

A day before the Valentine's Day, the "Suits" star and Prince Harry visited Edinburgh Castle in Scotland. Markle joined the Duke with a tartan coat and bottle green Strathberry East/West cross body bag. Less than a day after Markle's sighting the bag she used is already sold out.

Strathberry promises to restock East/West Mini variant that Markle used in Scotland. The bag is available in different colors including ruby edge, blossom yellow, black, ruby burgundy, slate, electric blue navy, dragon with edge, ruby, vanilla, tri colour navy/ruby/vanilla, and tri colour burgundy/navy/vanilla. But some of the other variants are already sold out too.

The spokesperson of Strathberry told Femail that they were pleased with Markle's move to use their brand in Scotland. They are also wishing Markle and Prince Harry the best for their royal wedding.

"We are pleased to welcome Prince Harry and Meghan Markle to Edinburgh on their first official visit to Scotland, and the support they are giving projects in our historic city is fantastic," the spokesperson said. "It is such an honour to see Meghan carrying a Strathberry bag again; this time an East / West Mini in Bottle Green. "

"We are especially thrilled that Meghan is carrying Strathberry in our home city and also after she chose to carry her Strathberry Midi Tote for her first royal engagement back in December. We wish them the very best for their upcoming nuptials," the spokesperson continued.

Markle made her royal debut a few days after she and Prince Harry announced their engagement. For the said sighting, the "Horrible Bosses" star stepped out in a black turtleneck bodysuit from Wolford, beige-chino style skirt from Joseph and over-the-knee-boots by Kurt Geiger. The royal bride-to-be accessorized her get up with a burgundy tote bag from Strathberry.

Strathberry spokesperson Leeanne Hundleby said that the brand received incredible interest after Markle used their bag when she made her first royal engagement. In fact, they struggled to keep up with the demands.

"The interest in the brand has been incredible," Hundleby told People. "The phones began ringing constantly and our visitor numbers on our website were up by around 5000 percent!"

The LINE The Label who created Markle's wrap-style coat on the said outing also experienced a massive increase in demand. "We are now dealing with the aftermath because everyone is trying to get it, but I don't want 10,000 white coats out there – it has to stay exclusive," John Muscat, president and co-founder of the brand said.
