The Story Behind Kate's 'Betty Boop' Hat
A £245 brown pillbox from Lock & Co, worn to parades, weddings and now a Sunday service at Balmoral: the story of the Princess of Wales's most repeated hat.
When the Princess of Wales stepped out for the royal family’s Sunday service at Crathie Kirk on 23 August 2026, sharp-eyed royal watchers clocked the hat before they had even registered the rest of the outfit. Small, brown, angled just so at the back of the head, it was the Lock & Co pillbox that fashion trackers nicknamed the “Betty Boop hat” more than a decade ago, out again for what is now one of her most repeated pieces.
It is a small hat with an outsized story. First seen in 2012, the Kate Middleton Betty Boop hat has since travelled from a St Patrick’s Day parade to a society wedding, a race meeting, a Christmas Day churchgoing and now a Highland kirk, at a reported cost of £245, which by the maths of repeat-wearing looks better value with every outing.
What is the “Betty Boop” hat?
The hat itself is a classic pillbox: a small, brimless, straight-sided shape that sits toward the back of the head rather than low over the brow, finished with a neat bow at the side. Lock & Co, the St James’s Street hatters that has dressed heads since 1676, makes it in a rich chestnut brown, and it retails for around £245, modest by couture standards, and positively frugal next to the tiaras and heirloom brooches that usually make royal-jewellery headlines.
The “Betty Boop” name is not an official Lock & Co title so much as shorthand coined by royal-style trackers, drawing on the hat’s saucy, slightly retro angle, the kind of jaunty tilt that recalls the 1930s cartoon flapper rather than a formal Sunday best. It has stuck precisely because it is so recognisable: no other royal hat in the Princess of Wales’s wardrobe gets spotted and named quite this fast when it reappears.
Every documented outing, from parade ground to pew
Royal style archives, led by outlets such as Hello! and the long-running fashion blog What Kate Wore, have tracked the hat’s outings for well over a decade. Among those on record:
- 17 March 2012: St Patrick’s Day Parade, Aldershot, its first public appearance as the then Duchess of Cambridge.
- 2 March 2013: the Bechtolsheimer-Tomlinson wedding.
- 15 March 2013: Cheltenham Festival.
- 25 December 2014: the Christmas Day walk to church at Sandringham.
- 17 March 2015: St Patrick’s Day Parade, a repeat of its debut engagement.
- 18 February 2016: a visit to RAF Valley in Anglesey.
- 23 August 2026: the Sunday service at Crathie Kirk, near Balmoral.
Fashion trackers count at least eight occasions across the hat’s fourteen-year run, alongside further sightings noted in royal-style archives that have not always attracted the same press attention. Whatever the exact tally, the pattern is unmistakable: this is not a one-season purchase but a genuine wardrobe fixture, reached for again and again across more than a decade of public life.
The latest sighting: a Sunday service at Balmoral
The most recent outing came during the royal family’s traditional summer stay at Balmoral, when the Prince and Princess of Wales joined The King and Queen for the Sunday service at Crathie Kirk, the small parish church the family has long attended while in Scotland. As is customary, Kensington Palace did not issue a styling note. The details below come from the fashion press and the royal-watcher accounts that track the Princess’s wardrobe outfit by outfit, among them Instagram’s @dresslikeaduchess (posting on 24 August 2026) and @kate_middletonwardrobe, rather than an official palace statement.
By their account, the Princess paired the Betty Boop hat with a herringbone tweed jacket, a high-necked, pie-crust-collar blouse widely attributed to Holland Cooper, and a pair of Ralph Lauren chandelier earrings described as “past-season” rather than new. Fashion writers called the overall look vintage-inspired and countrified, every inch the Highland Sunday best, built around a hat now old enough to have its own following.
A pillbox with Hollywood pedigree
The pillbox itself is older than any royal association. The style became a global fashion signature in the early 1960s through Jacqueline Kennedy, the American First Lady whose neat, structured pillboxes, usually worn tilted back, exactly as the Princess of Wales wears hers, turned a fairly plain hat shape into a symbol of understated, photogenic elegance. That legacy is part of why a brown pillbox photographs so well outside a church or at a parade: it frames the face without a brim getting in the way of the cameras, a practical advantage that has kept the shape in royal wardrobes for six decades.

The maths behind a £245 hat worn eight times
Cost-per-wear is the simplest way to think about it: divide what something cost by how many times it has been worn. At roughly £245 and at least eight outings, the Betty Boop hat now works out to about £30 per wear, a figure that keeps falling every time it reappears, and one that looks almost thrifty next to a wardrobe often estimated, across royal reporting, to cost somewhere between £50,000 and £200,000 a year once official engagements, occasion wear and accessories are all accounted for.
That contrast is deliberate, or at least consistent with everything else known about the Princess of Wales’s approach to clothes. She has re-worn a roughly £20 Zara prairie dress across engagements in 2020, 2021, 2023 and 2025; she wore an upcycled, one-shouldered Alexander McQueen gown to the BAFTAs in both 2019 and 2023; and for the 2022 Earthshot Prize ceremony she hired an emerald Solace London gown from the rental platform Hurr rather than buying new. Princess Anne, dubbed by royal watchers the original “queen of the re-wear,” has gone further still, resurfacing outfits decades old for official tours. A £245 hat worn eight times sits comfortably in that company.
Why the Princess keeps reaching for it
Part of the appeal is simply practical: a well-made hat in a versatile brown works with tweed, with a coat, with almost anything in a countryside or church setting, which is precisely where this hat tends to appear. But there is a more deliberate signal in the repetition, too. Where a headline-grabbing new outfit can trigger the so-called “Kate Effect” and sell out a High Street rail overnight, a favourite hat worn for the eighth time sends the opposite message: that not everything in a working wardrobe needs to be new to earn its place.
That instinct has become something of a hallmark. Whether it is a £20 dress or a £245 hat, the Princess of Wales has built a public reputation for getting proper use out of the pieces she likes, in a family whose clothing choices are watched, priced and discussed in more detail than almost anyone else’s.
Why it still matters
There is something quietly reassuring about a £245 hat with its own fan following. It suggests a wardrobe run on genuine preference rather than obligation to appear in something new, a small, brown, unshowy object that has outlasted several changes of title, several house styles, and at least one change of monarch.

What is the “Betty Boop” hat that Kate Middleton wears?
It is a brown pillbox hat by Lock & Co Hatters, priced at around £245, distinguished by a neat side bow and a brimless shape that sits toward the back of the head. “Betty Boop” is the nickname royal-style trackers have given it, not an official Lock & Co product name.
How many times has the Princess of Wales worn the Betty Boop hat?
Royal-style archives count at least eight documented outings between 2012 and 2026, including its debut at the 2012 St Patrick’s Day Parade and its most recent sighting at a Sunday service near Balmoral in August 2026.
When did the Princess of Wales first wear the Betty Boop hat?
The earliest recorded outing was 17 March 2012, at the St Patrick’s Day Parade in Aldershot, when she was still known as the Duchess of Cambridge.
Where did the Princess wear the hat most recently?
She wore it on Sunday 23 August 2026, for the traditional royal family Sunday service at Crathie Kirk, near the Balmoral estate in Scotland, per reporting from royal-watcher social accounts and the fashion press rather than an official palace statement.
Who makes the Betty Boop hat?
Lock & Co Hatters, the St James’s Street hat shop founded in 1676 and warranted to His Majesty The King, makes the hat. It is one of the world’s oldest continuously trading hatters.
Why is the pillbox style associated with elegance?
The pillbox became a global style signature in the early 1960s through Jacqueline Kennedy, whose structured, brimless hats, usually worn tilted back, offered an unobstructed, photogenic silhouette that remains flattering in official portraits and press photography today.
What does “cost per wear” mean, and how does it apply here?
Cost per wear divides an item’s price by the number of times it has been worn. At roughly £245 and at least eight outings, the Betty Boop hat now works out to about £30 per wear, a figure royal-style watchers point to as an example of getting genuine use from a wardrobe piece rather than buying new for each occasion.
Does the Princess of Wales often re-wear clothes?
Yes. Alongside the Betty Boop hat, she has repeated a roughly £20 Zara prairie dress across four separate engagements, worn an upcycled Alexander McQueen gown to the BAFTAs twice, and hired a gown for the 2022 Earthshot Prize ceremony rather than buying new.
