In fact, some people have been so enthusiastic to speculate on who the designer of the gown might be they've placed bets on it, leading to one betting company to suspend any bets on the topic after a flurry of people put money on fashion house Alexander McQueen being behind the historic gown.
According to bookmakers Paddy Power, a 'flood of bets' happened on Tuesday morning leading the odds to fall from16/1 to 8/1 this morning and then into the two's.
'Our traders have been inundated with bets for McQueen to be the designer of Meghan's dress this morning. So much so they've had to suspend the betting,' a spokesperson said. 'Either someone sneaky knows something, or there's plenty of shrewd punters who are up on their fashion knowledge.'
The spokesperson added to ELLE UK that they do not know why the huge influx of McQueen bets happened, it could be that they are 'in the know', 'have heard a whisper', may be fashion followers or could just be guessing.
They added that the last time they saw this level of betting on the Royal Wedding was just before Prince Harry proposed to Markle last year.
Sarah Burton, the creative director of Alexander McQueen, was famously the designer of Kate Middleton's royal wedding dress in 2011.
Only time will tell if Markle is to follow in the exact same footsteps of her new family member or will go a different route, though whoever she wears, it is likely it will be a British designer.
Aside from McQueen (who Meghan has already worn on a public outing with Prince Harry, since their engagement), there has also been speculation that Erdem, Ralph & Russo (who designed the beautiful dress she wore for those official engagement portraits), Giles Deacon or Victoria Beckham could be in the running - although the former Spice Girl recently said she has not been asked.
Other betting companies have not suspended betting just yet.
William Hill currently has Erdem and Roland Mouret as favourites, with McQueen at 20/1.
