"It was fantastic to see Meghan wear M&S, and we have been thrilled with the customer response", said a Marks & Spencer spokesperson.
In the past, she's expressed interest in "classic and simple" designs.
However, four months ahead of Harry's wedding to Meghan Markle in May, it seems the question still hasn't been popped.
Kensington Palace has confirmed that the 36-year-old actor and soon-to-be member of the Royal Family shuttered her Facebook, Twitter and Instagram accounts earlier this week, explaining that they "haven't been used for some time".
"When you're like minded, you go through similar things", William said.

Harry, 33, was William's best man at his 2011 wedding to Princess Kate.
In preparation for becoming the first Duchess of Sussex when she ties the knot with Prince Harry in spring 2018, Meghan Markle deleted all of her social media accounts.
William's children, Prince George and Princess Charlotte, are expected to play a role in the wedding, as they did previous year at the wedding of Kate's sister, Pippa Middleton, to financier James Matthews. That is, if Prince Harry ever gets around to asking him.
Harry, fifth-in-line to the throne, and actress Markle, best known for the TV legal drama "Suits", announced their engagement in November, with the wedding set for May at Queen Elizabeth's Windsor Castle home to the west of London. I would like to think that the world is a bit more evolved in the cerebellum. William said when asked by DJ Roman Kemp about his brother's big day and the importance of a best man. Of course I'd love to be there. The outlet reports that Thomas and Markle's half-sister Samantha have signed a "lucrative agreement to be filmed travelling from the United States to London for the [royal] wedding via a cruise". I'm very happy for them, Meghan and Harry.
It's admirable of Prince William to stand up and speak out not only about how important it is for men to open up about their feelings, but how one can truly benefit from leaning on a friend.
