She routinely wows on red carpets from New York to Paris.

And on Sunday evening reality star Olivia Palermo stayed true to form, dazzling at the La Traviata opening gala held at the Rome Opera House. 

The 30-year-old beauty was at once theatrical and ethereal, layering a sheer dress over a sexy black bodice.

The sheer dress featured a plunging neckline that showed off Olivia's stunning décolletage and gorgeous sun-kissed skin.  

Her assets were held in place with a frilly black bra, which added just the right amount of naughtiness to this heavenly look.

The gown featured countless golden stars, which matched The City star's chunky gold bracelet and her rectangular clutch, which shined with gold metallic embellishments. 

Power couple: Olivia's best accessory may have been her husband Johannes Huebl. The German model slipped into a classic tuxedo, replete with oversized bow tie, white handkerchief and black cumberbund

Olivia's most gorgeous accessory on the red carpet may have been her husband Johannes Huebl.

Well aware that Olivia loves the camera - and that the camera loves her - he stepped to the side to give his wife of nearly two years time to shine. 

Earlier in the day the loved-up couple enjoyed a spot of shopping, and Olivia was seen clutching a bag from La Perla, the Italian maker of fine lingerie.

In a recent interview with Harper's BAZAAR Australia, Olivia explained the secrets to their happy marriage: 'We try not to ever be separated more than seven days. It’s just something we have always done.'

But it doesn't look as though the genetically-blessed twosome will be hearing the pitter-patter of tiny feet any time soon, with the socialite admitting she is 'very focused on work' at present.

She added: 'I have my hands full and I have to prioritise.' 

Let's do this! Olivia and hubby Johannes seemed giddy and filled with the joys of summer as they arrived at the Opera House of Rome ahead of the gala

Suave: Johannes looked dashing with his hair slicked to the side and just the right amount of stubble on his glorious face
