After more than a year of campaigning, a new US president will soon be elected into the White House on Wednesday morning (Nov 9, Singapore time).

Democrat Hillary Clinton and Republican Donald Trump have tried to demonstrate they deserve to be in the Oval Office for the past 19 months.

But for now, here's a look back at their campaigning style - and we do mean, style.

1. TRAVELLING

TRUMP

Go big or go home - possibly what was running through Mr Trump's mind when he paid $100 million to buy a massive Boeing 757 from Microsoft's co-founder Paul Allen in 2011.

Despite the size of the plane, Mr Trump's refurbished version seats only 43 passengers.

It has been fitted with a master bedroom, a bathroom with 24-karat gold taps and basin, a shower, a dining room for 10, guest room and a lounge with a 52-inch flat screen TV, according to reports. Plus, the seat belts are 24-karat gold plated.

CLINTON

In comparison, Mrs Clinton's campaign plane seems tame. The interior of the 14-year-old Boeing 737 plane looks similar to commercial planes, as it is free of fancy embellishments apart from campaign posters, slogans and logos.

The plane, which is equipped with Wi-Fi, is divided into four cabins: one for Mrs Clinton and her aides, one for her campaign staff, one for the Secret Service and one with about 42 seats for the press.

2. DEBATING

TRUMP

The Republican candidate has been largely criticised for his fashion choices, particularly his suspiciously orange tan and coiffed hair. But his choice of suits has also been a target for fashion critics.

"The shoulders of his suits are too wide by at least a size, and slump over to the side. The jackets are a solid inch too long, and billow. The trousers, through bagginess, manage to look worn out, though they are not," said one Financial Times critic.

Fashion magazine GQ also provided a scathing review of Mr Trump's presidential debate outfits, questioning his choice of French cuffs - whose only purpose is to "show off cuff links" - and picking at the "weak" dimple in his tie.

But some observers believe Mr Trump's boxy suits are a deliberate choice that has only served him well politically. "Mr Trump is choosing to dress like a politician rather than a Wall Street financier and that helps him win support," said stylist Lauren Rothman in a BBC interview.

CLINTON

Did anyone notice that Mrs Clinton was actually decked in the US flag colours for the presidential debates?

The former secretary of state made a patriotic statement during the debates with Ralph Lauren pant suits for all three debates - staying true to her staple coat-and-trousers look.

At the first debate, she stunned with a bright red outfit that lent the 69-year-old a healthy glow. A fashion choice, perhaps, in response to revelations that the Democratic candidate was recently diagnosed with pneunomia.

The second debate saw Mrs Clinton in a navy blue suit, which The New York Times described as a "jovial-serenity-atop-policy-wonk approach with which she has chosen to contrast herself with Mr Trump".

To round off the debates, Mrs Clinton paid tribute to a historical women's rights movement with an all-white suit - similar to the one she wore when she accepted the Democratic Party's nomination as its presidential candidate on July 28.

The movement, which was led by the National Women's Party, established women's right to vote in the US. White was one of the official colours of the party.

3. CAMPAIGNING

TRUMP

Mr Trump's "Make America Great Again" baseball cap is probably one of the most iconic campaign paraphernalia of this US election season.

And it better be, as the Trump campaign has spent a majority of its campaign dollar on collateral from June 2015 to September 2016 - or US$3.2 million on the famous (or infamous) baseball caps, according to Federal Election Commission filings. The amount is more than what Mr Trump has spent on direct mail and polling.

The cap has inspired several spin-offs, including a "Make Mexico Great Again Also" cap that was worn by former New York Mayor Rudy Giuliani at a Trump rally.

The Clinton camp has tried to mock Mr Trump with their own take on the baseball cap, such as a make-it-yourself "tin foil" cap.

Comedian and host John Oliver, who has criticised Mr Trump publicly, is also selling his own cap: "Make Donald Drumpf Again". Drumpf was the original family name of Mr Trump's ancestors.

CLINTON

Here is a lesson on how to use a jab from your rival to your benefit: Turn it into campaign paraphernalia.

During a victory speech on April 26, Mr Trump had this to say about Mrs Clinton: "Frankly, if Hillary Clinton were a man, I don't think she'd get 5 per cent of the vote. The only thing she's got going is the woman's card."

Within hours of the comment, the Clinton camp released a literal woman card, and successfully capitalised on Mr Trump's attack.

Her campaign raised $26.4 million that month, with 115,000 individual donors within three days after Mr Trump's comments. And nearly half of the donors were donating for the first time to the Clinton campaign, according to The New York Times.
