Like a diamond-encrusted thief in the night, the Venice Film Festival creeps up on you.

Smack bang in the middle of the awards dry season, and with the focus firmly on the films and filmmakers rather who's wearing what and what pretend celebrity rivalries are brewing, the dazzling award show kicks off with a composed sense of professionalism and elegance.

That said, it is truly one of the highlights of the fashion calendar, with attendees seeming to embody the slightly avant-garde and European feel of the festival, turning heads in outfits rarely seen on the Oscar red carpet. 

Case in point: Iman. 

Leave it to one of the original supermodels to make a grand entrance, and that she did, wowing in two extravagant gowns by Valentino. The first, a ruffled purple confection with sheer paneling on the bust - major props to Iman for not being afraid to free the nipple - and dramatic shoulder detailing.

The second - an opulent cape gown emblazoned with Japanese-inspired birds and flowers, and trimmed at the wrists and neck with feathers - was jaw-dropping, glamorous enough to be worthy of a woman with Iman's credentials, while also looking a little like a fancy duvet. It's a yes from us. 

Our own Ruth Negga made an appearance on the red carpet, first dazzling in a geometric gold and silver jumpsuit by Nicolas Ghesquiere, jewellery by Beladora Jewelry and Louis Vuitton and a pair of striking circular sunglasses that perfectly suited the intergalactic vibe of the Ad Astra premier.

Later, she wowed us again in a feminine Louis Vuitton look, wearing an embroidered white dress, nipped at the waist by a wide white belt and finished with a white bolero. 

Scarlett Johansson brought her characteristic Old Hollywood glamour to the red carpet, looking beautiful in a red sequin Celine gown featuring a thigh-high slit and sweetheart neckline, given an edgier update with slicked back hair and earrings with a chain detail. 

Meanwhile, Kate Upton also upped the drama in a full-length black Twinset gown with a daring slit and a statement snake necklace.

The film festival is also an opportunity for us to see stars we rarely do on the main awards circuit, such as Liv Tyler who walked the red carpet in a voluminous Givenchy black satin gown, featuring dramatic off-the-shoulder detailing. 

Showing that opulence has a home at the Venice Film Festival, Laura Dern stunned in a glittering emerald green gucci gown featuring a sheer overlay, a red velvet trim and intricate silver embroidery. 

Ask anyone who stole the show, however, and the answer will probably be Brad Pitt. Brad Pitt: the man who can show up with slightly disheveled hair and a black suit and send Karla Welch - celebrity stylish behind the looks of Julianne Moore, Tracee Ellis Ross and Ruth Negga - into a frenzy. She even managed to snap a photo of him, writing "I thought the sky was going to crack open, it was so electric!"
