30 photos of Princess Beatrice’s wildest hats that prove she's the reigning queen of headwear

Even from a young age, Princess Beatrice knew how to rock a stylish hat.

Princesses Beatrice and Eugenie attend a Christmas Day service at  St. Mary's Church in Sandringham, England, in 2002 with their father, Prince Andrew, Duke of York.

As the fifth grandchild of Queen Elizabeth, she's always had a great hat role model.

Princesses Beatrice and Eugenie help their grandmother, Queen Elizabeth, receive flowers after the Christmas Day service at St. Mary's Church in Sandringham, England, in 2005. 

The Royal Ascot is the perfect occasion for delightful headwear — like this classy black and white hat Princess Beatrice wore in 2008.

The Royal Ascot, a weeklong series of horse races, always attracts some wild hats.

She wore this white floral hat at the 2009 event.

At the Royal Ascot 2011, she matched her hat to her jacket.

This hat appears to be inspired by a blueberry bush.

Princess Beatrice also went for a matching combo at the Royal Ascot 2012. Although the hat was more understated than some of her other looks, it balanced out the appliquéd details of her dress.

She wore the red and cream ensemble for "Ladies' Day", a celebration of women's Royal Ascot fashion. While the phrase was coined by a 19th-century poet, the day itself is not officially on the Ascot agenda.

Princess Beatrice wore this feathered percher hat to the Royal Ascot 2016.

It was designed by Sarah Cant.

At the Royal Ascot 2017, she wore a black straw hat adorned with white lace flowers.

It was designed by Nerida Fraiman.

She also wore this feathered saucer hat to the 2017 event.

It was designed by Vivien Sheriff.

Princesses Beatrice and Eugenie both looked polished at the Royal Ascot 2018.

Princess Beatrice's powder-blue hat was designed by Juliette Botterill.

The Philip Treacy fascinator she wore to Prince William and Kate Middleton's wedding remains one of her most iconic looks.

While the bow-inspired hat sparked numerous memes, Marie Claire reported that it was auctioned off on eBay for charity. The winning bid was $109,435. 

She wore this memorable butterfly fascinator to the wedding of her cousin Peter Phillips and Autumn Kelly.

It was also a custom Philip Treacy creation.

She wore this eye-catching blue hat to another family wedding — the marriage of her cousin Zara Phillips and rugby captain Mike Tindall.

Dr. Julian De Silva , a plastic surgeon based in England, used facial mapping techniques to analyze the features and proportions of male and female members of the royal family to see which are the most attractive. In the men's category, Mike Tindall came in at fourth place with 76.7% accuracy.

This navy and cream percher — designed by Gina Foster — is among Princess Beatrice's notable holiday looks.

Princess Beatrice wore it to a Maundy Thursday (aka Holy Thursday) service in York, England. The Christian holy day falls on the Thursday before Easter.

She accompanied Queen Elizabeth and Prince Philip to the service as part of the queen's Diamond Jubilee celebrations. 

She donned this elegant hat for Easter in 2011.

In 2013, she wore this yellow felt beret for Easter.

Designed by Rachel Black, this hat is accented with a chic ombre feather.

For Easter 2015, she stood out with a poofy blue cocktail hat — yet another Philip Treacy creation.

The feathers-and-flower combo made this hat pop.

She wore it for Christmas in 2010.

In fact, she's worn floral hats for Christmas over the years — like this fun fascinator.

The flower stands out against the checkered print.

Or this blue velvet number.

Of course, florals are also a natural choice for a garden party.

But she's also taken the playful route when it comes to garden party attire.

At the 2016 Not Forgotten Association Garden Party, she wore a whimsical felt fascinator bedecked with pink leaves.

Trooping the Colour, a celebration of Queen Elizabeth's birthday, is yet another occasion that calls for great hats. From this frilly cream-colored style...

Trooping the Colour is one of five ways England celebrates Queen Elizabeth's birthday every year.

...to this structured hat reminiscent of an orange peel.

Of course, the queen herself wore some fabulous headwear to the event over the years.

Even her version of simple has a bit of pizzazz.

She kept it whismical and light with this oversized sun hat on day four of the Royal Ascot races in 2016.

But when she wants to, she can make a bold statement — like with this golden-glazed topper.

Both hats appear to have been inspired by Easter eggs.

Princess Beatrice appears to have taken notes from her mother, Sarah Ferguson, Duchess of York.

Princess Beatrice, Dave Clark, Sarah, Duchess of York, and Princess Eugenie are color-coordinated as they watch the races at the Royal Ascot in 2015 — and Sarah's blue hat gives her daughter's a run for its money.

Sometimes, she's in a black-and-white mood — like at the Royal Ascot in 2018.

This day-three hat was accented with dark flowers — and looked similar to Meghan Markle's minimalist, sideswept number.

But most times, she likes her hats bright and colorful.

This violet and orange hat is color-blocking at its finest.

From whimsical to glamorous, Princess Beatrice's hats always help her stand out.

Following the National Service of Thanksgiving — an event held in 2016 to commemorate Queen Elizabeth's 90th birthday — Princess Beatrice attends a lunch at Guildhall.
