Princess Beatrice suffers wardrobe malfunction in semi-sheer dress at London bash
The definition of what's considered "racy" definitely changes when you're a royal.
For some actresses, it's a thigh high split and plunging neckline, for Kate Middleton, it's a sleeveless top. But without the pressure of strict royal codes to adhere to, Princess Beatrice has a little more wiggle room in the fashion department than her cousins.
The business consultant (28) ensured all eyes were on her as she opted for a navy blue, semi-sheer Self Portrait dress to celebrate the V&A Museum's summer party on Wednesday night.
The sheer panelling alone would likely ruffle royal feathers, but the young princess inadvertently showed off her nude shapewear under the flash of the cameras as she made her way into the museum.
Her grandmother, Britain's Queen Elizabeth is famously conscious about avoiding any unwanted displays and as their longest reigning monarch, she has picked up a trick or two along the way.
In order to avoid a 'Marilyn moment' like Middleton has in the past, she lines the hem of her skirts with stones so as to avoid the aftermath of a gust of wind - not to mention the fact that she has a person on staff whose sole (pun intended) job is to break in her new shoes.
But she likely doesn't have anything in her rule book for showing off your high-wasted underwear under your sheer high street dress. Beatrice's younger sister Eugenie joined her for the occasion, alongside her boyfriend Jack Brooksbank and the pair have been busy socialising at the royal box at Ascot Racecourse this week, showcasing their unique style.
As expected, the royal sisters have opted for eye-catching ensembles: Eugenie in a dramatic red midi-length dress with powder blue and red hat and Eugenie in a blue and black number.
And we're so thankful for it.
