Meghan Markle, 2018 -

The Duchess of Sussex was wearing this gorgeous red dress when she arrived in Tonga in October 2018. What's the problem, you ask? She left the tag on the bottom of the dress and it was visible!

Sarah Ferguson, 1988 -

Okay, Ferguson was attending a fashion show in Los Angeles. But still, there is hardly ever a good reason to look like a mix of Carmen Miranda and a Flamenco dancer.

Prince William, 2019 -

We love it when royals display their frugality, but those shoes really need to be replaced (yes, that's a hole!).

Queen Máxima of the Netherlands, 2005 -

Not even a queen should walk down the red carpet dressed in an Amazon rain forest-inspired gown.

Sarah Ferguson, 1997 -

As you'll see throughout this gallery, the Duchess of York is a champ when it comes to faux pas moments, including this post-it note style look.

Princess Beatrice And Princess Eugenie, 2011 -

It's easy to see why the outfits they wore for Kate Middleton and Prince William's wedding became famous on the internet. There was even a meme comparing them with the stepsisters in 'Cinderella.'

Sarah Ferguson, 1987 -

"Aw, what a cute '80s wedding dress," one might think. Except it wasn't for a wedding.

Charlotte Casiraghi, 2016 -

Monaco's Charlotte Casiraghi wore this black and gold mini-dress to the Vogue Foundation Gala in 2016. It has more hectic detail than a Renaissance painting.

Kate Middleton, 2012 -

The faux pas here is not exactly the dress, but the fact that this is a traditional outfit from the Cook Islands. What's wrong with that, you ask? Well, she mistakenly wore it on her visit to the Solomon Islands and it was quite offensive for the locals.

Queen Letizia Of Spain, 2004 -

That pink frock would probably have passed in the '90s, but it just looks weird if you're attending a wedding in the 21st century.

Princess Beatrice, 2008 -

If you've ever wondered how a royal would look like dressed as a rainbow popsicle, this is it.

Princess Diana, 1981 -

Was Princess Diana wearing a costume on her way to a child's birthday party to work as an entertainer? No, Lady Di was actually attending the 1981 Royal Ascot horse race.

Zara Tindall, 2007 -

There's a lot of things wrong with this look, but the sequin belt really takes the cake.

Sarah Ferguson, 1987 -

The Duchess of York did not disappoint (again) at the Cafe Society Royal Ball. The polka-dot dress is indeed very cute—if you're a 1950s pin-up model.

Princess Anne, 1995 -

This fruity look she wore to the Royal Ascot was not nearly as sweetly received as she probably intended.

Sarah Ferguson, 1988 -

It's impressive how often the Duchess of York can get it wrong. This is a bit too much for a Naval Staff dinner, don't you think?

Sarah Ferguson, 1986 -

'Little House on the Prairie,' anyone? She does look cute, though. In a vintage table cloth kind of way.

Zara Phillips, 2013 -

Neither the shape nor the color of that gown is doing Zara Phillips any favors.

Princess Anne, 1985 -

Okay, it was the '80s, so ruffled shoulders were a thing. But maybe for a movie premiere she should have toned it down a little?

Charlene Wittstock, 2012 -

The color doesn't match her complexion very well, but the worst is really that super cropped jacket.

Princess Beatrice, 2017 -

Princess Beatrice wore this dress, which appears to have been made with a Victorian lace curtain, to the V&A summer party in 2017.

Queen Máxima of The Netherlands, 2018 -

Queen Máxima usually has a great fashion sense, but on this occasion she missed the mark. This is a great example of how one should not mix patterns.

Princess Victoria Of Sweden, 2004 -

This lime green dress with lace detail was not a great choice for the wedding of Frederik, Crown Prince of Denmark and Mary, Crown Princess of Denmark.

© Getty Images

Sarah Ferguson, 1986 -

We're not criticizing every single '80s dress, but what's this one made of? Cinderella fabric, perhaps?

© Getty Images

Zara Tindall, 2008 -

We get it, the Royal Ascot is all about the hats. But it helps when the rest of the outfit works too. 

© Getty Images

Zara Tindall, 2005 -

There is just a bit too much going on. That print dress needs to breathe, and the black hat and boots are suffocating it. 

© Getty Images

Princess Anne, 1989 -

This is such thing as too much matching. Here's a fine example.
