Oh. Fans noticed something a little awkward about one of Meghan Markle's Sydney dresses.

Oh, hello.

Here in Australia we have a brand new hobby and it can be summed up as follows: royals. 

We like facts about the royals, stories about the royals, people’s interactions with the royals, and also clothing and/or accessories worn by the royals.

By royals, we obviously just mean Meghan Markle and Prince Harry, because since they came to visit they’ve been everyone’s favourite guests. They cuddle the children, they’re polite to our super embarrassing prime minister (ScoMo, pls), and graciously accept our terrible gifts.

But, as with any important guests, we’re watching them very closely. To the point where it is problematic on many levels. And the people who have now quit their jobs and only ingest things that are royal-related have noticed something.

It’s about the dress Meghan Markle wore to the opening of the new ANZAC Memorial in Sydney’s Hyde Park on Saturday.

The dress, a piece by New Zealand designer Emilia Wickstead, was paired with a fascinator by Irish designer Philip Treacy - a look Markle reportedly selected with the help of her best friend, stylist Jessica Mulroney.

But, to some people, it looked familiar.

Some people, it would seem, who are very, very obsessed with Prince Harry.

Because back in June, one of Prince Harry's ex-girlfriends, British actress Jenna Coleman, wore the white version of the dress to a polo event.

Coleman reportedly dated Prince Harry in 2015, but their "schedules" prevented the relationship from becoming serious.

GUYS.

THIS IS VERY IMPORTANT.

Two women who know a person in common wore the same dress (but not quite) to two different events.

WHY HAVE I SPENT THE LAST HALF AN HOUR GOOGLING JENNA COLEMAN.

There is something very wrong here, and it has nothing to do with Meghan Markle and Jenna Coleman 'accidentally twinning,' as the tabloids are calling it, and everything to do with us needing to get a new hobby.

But also, 'royal fans' should become detectives because they'd be very... efficient.

For the record - it's rumoured Meghan chose the dress to wear to the ANZAC event because of its New Zealand designer, a subtle way to acknowledge the alliance between Australia and New Zealand, and to honour the efforts, contributions and sacrifices made by the two nations.

It probs had precisely zero to do with Coleman.
