Naturally, it didn't take Twitter long to pick up on the comparison, putting images of Meghan next to a photo of Wallis taken in 1936, with some noting not only the similarities between their ensembles, but their lives, as Wallis Simpson's husband, the then-King Edward VIII abdicated the throne to marry his American divorcee lover.
Of course, it should be noted that Wallis' controversy extended beyond being a divorced American woman who fell in love with a royal, but that she and Edward were thought to have been Nazi sympathisers at the time.
It's not the first comparison that's been made in regard to Meghan's outfit. When initial clips emerged of the interview, royal watchers were quick to note that she was wearing one of Princess Diana's bracelets for the momentous interview, surmising that her look may be sending two hidden messages.
Per People, the couple wanted Meghan to wear the bracelet during the interview so "Diana could be with them", with the piece in question also forming the inspiration for Meghan's engagement ring, as Prince Harry took two stones from the heirloom to create the Duchess' famous three-stone ring.
Fans have also noted that along with potential references to Wallis Simpson and the honouring of Princess Diana, the lotus on Meghan's dress holds significant spiritual meaning in symbolism, signifying rebirth and enlightenment.
Per Town & Country, it's also considered a particularly resilient flower, with the capacity to flourish despite its challenging surroundings: "With such refusal to accept defeat, it's almost impossible not to associate this flower with unwavering faith. Although cultures have largely dubbed the lotus as a spiritual figurehead, it is most emblematic of the faith within ourselves."
Meghan Markle and Prince Harry's interview with Oprah airs in Australia tonight at 7:30 pm AEDT on Network 10 and 10 Play.
