Fast forward to Tuesday and now, once again, people think they've cracked the royal Da Vinci Code of clothing.
One of these lucky recipients included Moortown, U.K. resident Edna Levi, who said she was so "thrilled" with the engagement news that she personally wrote the couple a note of congratulations.
Ms Daley, clutching a "Happy Engagement" balloon, brought along her Cavalier King Charles Spaniel, named Camilla, to meet the couple. (And for what it's worth, it seems like Prince William and Prince Harry are on board, too.) For instance, the sheer fact that Meghan was invited to Christmas at Sandringham is a big "tradition breaker".
Cardiff Castle is now hosting the Welsh Culture Festival and during their tour of the castle, Prince Harry and Meghan heard performances from musicians and poets. Harry and Meghan were welcomed at the manor by scores of fans.
Prince Harry and Meghan Markle's wedding is only four months away, and the couple is busy putting together an exclusive guest list that will include celebrities, royals, and dignitaries from around the world.
The visit included a stop at Cardiff Castle.
She also carried a mini-saddlebag-shaped purse in forest green by the British brand Demellier, according to the blogs that track her fashion.
It's thought that it was chosen for Meghan because she's an avid cook. Harry was dressed casually in a black overcoat with a bright blue sweater over a white shirt.
The American star also wore a long, black £1,350 Stella McCartney tie detail coat with peak lapels, a V-neckline and oversized waist tie.
Among the plates, posters and mugs with the 32-year-old and his bride-to-be's face emblazoned on the front, royal admirers can now get their hands on Harry and Meghan dolls. "They were so cute honestly", an eyewitness shared.
So far, the United Kingdom crowds have been loving the royal bride-to-be.
