And after Prince Harry finally announced his engagement, the happy couple embarked on their first royal photocall and interview.
Amid the excitement of letting royal fans in on the meaning behind Meghan Markle’s stunning engagement ring, there was another thing that caught everyone’s attention.
Meghan’s incredible outfits have already become the UK’s style obsession, with her white coat causing chaos.
Cleary, the Meghan Markle Effect is already sweeping the nation.
But before Meghan was dishing out style inspiration, the Kate Middleton Effect was well and truly alive.
And the sensation really kicked-off, in much the same way as Meghan, when the Duchess and Duke of Cambridge posed for their royal engagement photocall in 2010.

Kate, 35, posed next to Prince William in a royal blue wrap dress from Issa, a brand next to no-one had heard of back then.
But within 24 hours, their small business was sent into complete overdrive.
With pictures of Kate and Wills being published worldwide, the London-based designer explained how her phone did not stop ringing throughout the night.
Within five minutes, the look picked by the future royal sold out.
Daniella Helayel, the brand creator took thousands of orders and went on to create dresses for international celebrities such as Scarlett Johansson and Jennifer Lopez.
While promoting the small, local business seems like an amazing thing initially, the sheer scale of the demand soon got too much for Daniella.
She previously told the Daily Mail: “We didn’t have a TV at the studio and this was pre-Instagram, but we soon knew Kate was wearing Issa because at four o’clock the phones began ringing and didn’t stop. It was bonkers.”
From the day of the royal engagement back in 2010, the small company’s sales doubled.
But sadly she had neither the staff or equipment to fulfil such demand, let alone the money.
“I didn’t have the money to finance production on that scale. The bank refused to give me credit, and the factory was screaming for me to pay its bills. I needed an investor,” she said.
It turned out to be too much pressure for the London designer as she revealed: “I felt so stressed that my hair went white and started falling out. I was broken by the end of it. I had a great business, which I’d built up on my own over a decade. To watch it evaporate was heartbreaking.”
With fascination over Kate’s outfits only growing over the years (especially throughout her third pregnancy) we can only imagine the same will happen with Meghan. Let’s hope her favourite brands can keep up with the overwhelming demand!
