Golden girl! Giuliana Rancic chooses glittering gown by Australian designer Steven Khalil for her final look at the Miss USA pageant

Giuliana Rancic has modeled some of Australia's premiere designers on major red carpets this year, and Monday night's Miss USA pageant was no different.

The E! News anchor had three wardrobe changes for her co-hosting gig, closing the evening in a breathtaking Steven Khalil gown.

The ravishing look was from the Australian label's Fall 2014 collection.

The sheer, plunging gown featured intricate matte gold sequin detailing with subtle flecks of lilac and a hip-skimming split.

Giuliana's frock dazzled against her olive skin and her chocolate hair was pulled back into a centred pony tail which only accentuated the dresses impressive detailing.

The leggy brunette shared a snap of herself with pageant co-host Thomas Roberts, captioned: 'Third and final look of the night! Gown by @steven_khalil #missusa.'

Giuliana has been a strong supporter of Australian fashion designers on the red carpet this year.

At this year's Grammy Awards the stunning Italian-born American wore a tangerine gown from Alex Perry's Cruise 2013 collection and then followed it up with a princess look at the Oscars in Paolo Sebastian.

However, it wasn't all smooth sailing for the fashionista on Oscar's night.

'I'm all about Australian designers right now,' she gushed as she talked through the Paolo Sebastian dress. 'I feel princess-y — a girl deserves to feel like a princess once in a while.'

Unfortunately Giuliana's princess bubble was soon burst when the zip on the dress broke open on live TV.
