Nicky Hilton puts on a VERY cheeky display at Versace show in a white dress that leaves little to the imagination... just days before her wedding to James Rothschild

She usually leaves the fashion faux-pas to her older sister Paris.

But Nicky Hilton was the talk of the town on Sunday night when she attended the Atelier Versace show during Paris Fashion Week Haute Couture, revealing a little more than she bargained for in a see-through dress.

The 31-year-old hotel heiress put on a very cheeky display in her thigh-skimming white shift with sheer panels, flashing her entire derriere as she ascended the steps of the Palais Brongniart.

Nicky shunned underwear in her futuristic number, which boasted circular cut-outs of varying sizes.

A transparent band under the bust showed off a subtle hint of her toned stomach, but the matching panel at the bottom of the dress wasn't quite so strategically placed.

The star revealed she had gone commando as she turned around, showing off her pert bottom to the crowd.

Oh Nicky! How ironic is it to step out for fashion week in Paris for the Versace Haute Couture Show wearing a VERSACE dress that caused her to have a fashion no-no!

The dress itself is cute, don't get us wrong...but maybe wear some nude undies next time Nicky, it will help you in the long run.

Ladies and gentleman, if you can shift your attention from her derriere and go further south toward her feet you will see a gorgeous pair of jeweled Christian Louboutin pumps.

These lace designed puppies are the 'Top Vague' pump and can be yours for $2995 at ChristianLouboutin.com (click right).

Nicky seemed unaware of her wardrobe malfunction, however, flashing a big grin and a jovial wave to the crowd.

The socialite is due to the knot with banking scion James Rothschild this Friday and guests at their Kensington Palace wedding could be in for a spectacle if the dress she wore to the catwalk event is anything to go by.

Let’s hope that Valentino, the Italian designer rumoured to be creating her bridal gown, opts for something a little more tasteful.

Nicky and James have been dating since 2011, and the wealthy Brit proposed last August while visiting Italy's Lake Como.

The blonde beauty has had several festive events leading up to that, including a princess-themed wedding shower in May and a Miami-based bachelorette party at the beginning of June.

This will actually mark the second wedding for Nicky, who married childhood friend Todd Andrew Meister in Las Vegas 10 years ago, only for the marriage to be annulled three months later.
