Malcolm Turnbull's leather jacket

The Prime Minister saved the best for last, sartorially speaking. In the final weeks of the election campaign Malcolm Turnbull brought out the big guns – his infamous leather jacket. The same jacket he debuted on Q&A when he wooed progressive Australians with talk of marriage equality and plans to tackle climate change. While he auctioned off the black version for charity, his brown Top Gun-esque jacket made an appearance on the campaign in Melbourne recently. Admitting he copped "flak" for donning leather before, fashion experts suggest he should have invested in a bomber style to be more on trend for the winter election. "You can buy conservative ones from Sportscraft or edgier from Acne," celebrity stylist Mickey Ayoubi said.

Michaelia Cash's red manicure

The Minister for Women, like Foreign Affairs Minister Julie Bishop, is partial to a bright manicure, which is a strategic grooming tactic according to colour experts. As well as her bold Carla Zampatti and Bianca Spender suits, Cash has been sporting red talons on her extensive, nationwide campaign trail. "Research indicates that red has an 'attentional advantage'", says visual literacy expert Zena O'Connor. "Wear red and it automatically draws attention. Red is also considered to convey a sense of excitement and vitality."

Julie Bishop's jackets

The brooches that usually dominate Question Time have taken a back seat during the campaign and replaced by the latest in autumn-winter jackets. As she traverses the country two things have consistently been in her style arsenal – her 2XU running tights at dawn and, from sunrise to sunset, blazers by Australian designers Dion Lee, Camilla and Marc, Carla Zampatti and Bianca Spender. "I've always had a deep appreciation for fashion and our designers are world class," she says. For evening appearances, like her campaign launch in Perth, the Foreign Affairs Minister employs lots of sparkle via sequin encrusted jackets and block-coloured Giorgio Armani pant suits.

Bill Shorten's active wear

The Opposition Leader has tackled the campaign like Hollywood stars prepare for awards season, by dropping a lot of weight. Shorten, according to wife Chloe is "a very good, committed runner" and if nothing else will have conquered the Couch to 5K regime following the eight-week election campaign. But to complement his new svelte silhouette, experts say he needs to take a leaf out of Bishop's active-wear rule book – make sure compression is key and "avoid some of the more garish coloured offerings," GQ Australia fashion editor Brad Homes says. "I think it would be great to see him sporting some strong new sartorial additions to his wardrobe, outside the regular boxy, blue suit."

Barnaby Joyce's hats

The Agriculture Minister's most popular item during the campaign has been his headwear. Whether it's the Nundle Dog Races or a rodeo in Tamworth, where Joyce goes, an Akubra follows. Earlier in the campaign the Deputy Prime Minister acquired a second hat and instead of consulting a stylist, canvassed Facebook for fashion advice. "I've announced millions of dollars for new dams and inland rail this week but my new hat is getting all the attention," he wrote. "Now, I've got two hats and only one head. Which hat do you think is best?" Thirty-nine per cent of voters suggested he "Keep both hats. Lose the head", while his "new cream hat" came in a close second with 38 per cent of the vote.

Carlie Fowler

While she has not been as prominent on the campaign trail as other political significant others, Fowler – should things go to plan for her partner James Mathison, who is standing as an independent in Tony Abbott's seat of Warringah – could become our own Carla Bruni. The former Estee Lauder and sass & bide publicist turned beauty blogger rarely puts a sartorial foot wrong, and her laid-back style is a favourite of US celebrity stylist Rachel Zoe. Fowler, the prospective First Lady of Warringah, attended Fashion Week in Sydney last month wearing jeans and a black turtle neck, a polished yet pedestrian look that was celebrated by US Harper's Bazaar and The Zoe Report.

Christopher Pyne's vest

Focus groups have reportedly labelled the Prime Minister "old and tired" when he wears a knit, however "The Fixer" donned an Australian woollen vest this week to hit the hustings and resembled a relaxed Captain von Trapp from The Sound of Music. Pyne opted for a grey marle hue which complimented his crisp white collar, red, mustard and navy striped tie – a look that has the potential to overshadow his popular "Pyne Delivers" election merchandise and eco-friendly shopping bags.
