The Duchess of Sussex paired the tiara with a £25 T-shirt

The Duchess of Sussex marked her 45th birthday on Tuesday with a joyful clip posted on social media, offering fans a glimpse of her celebrations at home in California.

In the video, Meghan Markle can be seen dancing barefoot through her kitchen, sporting a glittering "Happy Birthday" tiara purchased from the American retailer Target.

Prince Harry was behind the camera, capturing the lighthearted moment as his wife twirled and laughed among birthday balloons.

The relaxed, candid footage stood in sharp contrast to the more formal approach typically associated with senior members of the Royal Family.

The fashion blog What Meghan Wore identified the duchess's white slogan T-shirt, which bore the phrase "It's Giving Mrs," as a £25 piece from Etsy.

She completed the all-white ensemble with relaxed pyjama trousers from the premium label Eberjey.

The combination of a budget tiara, an affordable slogan top and luxury loungewear encapsulated Meghan's approach to fashion, mixing high and low price points with apparent ease.

In contrast, the Princess of Wales is also known to favour classic, enduring pieces over fleeting fashion trends, and a slogan tee falls into the latter category.

Furthermore, while the Waleses do occasionally share personal content on social media, footage filmed inside their private living spaces remains exceptionally rare.

In 2024, she sported a tee bearing the slogan "Love like a mother" in bold red lettering, produced by the charity Alliance of Moms for their annual campaign.

Proceeds from the shirt went towards "essential services, education, and advocacy so that young parents in foster care and their children can heal and thrive," the organisation said on Instagram.

The broader trend for slogan tees, a hallmark of early-2000s celebrity style, experienced a notable revival in 2023, with figures such as Hailey Bieber and Bella Hadid embracing the look.

Victoria Beckham remains perhaps the most iconic proponent, having worn memorable examples including tops reading "Fashion stole my smile."
