Princess Eugenie is a royal rule-breaker in sheer mini-dress and risque stilettos we can't believe

Princess Eugenie's 2010s fashion is nothing short of fabulous, so we can't help but hark back to throwback looks from time to time. 

One of our favourites has to be this elegant minidress worn by the royal at the Serpentine Gallery Summer Party in 2014.

The masterpiece in question was an elegant chiffon baby blue number, paired by Eugenie with the tallest pair of stilettos we've ever seen a member of the royal family wear.

Eugenie's killer heels were peach with an early-2010s-style cork heel, complete with a peep-toe detailing, exposing the Princess' immaculately polished red toes.

For the summer evening, the then 24-year-old Princess styled her dark brunette tresses into perfect curls, framing her camera-ready makeup.

Her glam was comprised of dark black eyeliner, nude lipstick and warm honey-hued bronzer.

Euegenie's ensemble was complete with a pair of elegant drop earrings.

Eugenie's best throwback looks

Another of our favourite looks from the British royal is a look she wore while attending the Epsom Derby.

Aged 21,  Eugenie slipped into a white capped-sleeve mini dress adorned with black polka-dots, which she wore while attending the Epsom racecourse.

Her monochrome ensemble was complete with an empire-line black belt, accentuating her waist, a black-and-white straw hat and another killer pair of peep-toe stilettos.

This time, Eugenie's choice of shoes featured an elegant ankle strap, the perfect pair for her black and white ensemble. 

When Eugenie was 26, she opened up about wearing killer heels during an interview with Harper's Bazaar.

"I've started wearing high heels, which is so grown-up", she said at the time, adding: "But they're painful by the end of the day. I look at people wearing heels in movies, and I'm like, 'How do they do that?'"

Of her go-to shops, she said: "For clothes, I love Sandro and Maje. Zara is great for work, and bits from Topshop. My favourite is my lace bomber jacket from Essentiel Antwerp. And I live in my Rag & Bone ankle boots."

Eugenie continued: "I love trying new looks. I don't want to be pigeonholed. You wear the same thing twice? Great. If you don't, great! And if that means wearing a green Sandro dress, great. I wore that to Granny's birthday parade, with a Vivien Sheriff hat. I also wore this amazing red Eponine dress for Granny's 90th-birthday service at St. Paul's."
