Image source, Getty ImagesMelania Trump kicked off inauguration day with an outfit that has all the hallmarks of her favoured First Lady style: sharply cut, with spiked heels and a dramatic flourish via the headgear.
It is simultaneously serious and chic. It also speaks to her love of hats – see for one example her widely criticised colonial-style pith helmet on safari in Kenya, external.
Hats have long been a staple of First Lady inauguration dressing, from Jackie Kennedy's pillbox hat to the hats worn by Nancy Reagan to each of her husband's inaugurations, the first one "Reagan red" and the second one blue.
But while some hats feel like an addendum to an outfit, others take on more main character energy – as does Melania Trump's today.
The brim is wide enough and the contrast between the cream ribbon and navy hat big enough that it draws the eyes upwards – even if Melania's eyes remain somewhat hidden underneath.

It’s not a long drive from the White House to the US Capitol, but the presidential limousine – which Donald Trump and Joe Biden shared this morning – took it slowly.
Typically, the Pennsylvania Avenue route is full of onlookers gathering for the inaugural parade later in the afternoon.
Today, with all the ceremonies moved indoors and the main public viewing area - and parade - at a sport arena a few blocks to the north, the crowds were relatively sparse.
The folks who did brave the cold, however, welcomed the passing motorcade with cheers.
Donald Trump has just arrived at the Capitol, where the main proceedings of today's inauguration will take place.
He walked in side by side with outgoing President Joe Biden.
Joe Biden and Donald Trump are car pooling to the Capitol building, as they head to the inauguration ceremony.
The pair are in a limo, which is in a massive convoy of various police and secret service vehicles.
And around them, the streets are lined by hundreds of personnel, designed to keep the two top men of the country safe.

People have just started arriving at the Capitol, where the indoor inauguration ceremony is set to take place shortly.
Among them are Republican lawmakers and allies of Donald Trump, including House Representative Marjorie Taylor Greene of Georgia, as well as Kentucky Senator Mitch McConnell with his wife Elaine Chao.
Former Republican US house speaker Kevin McCarthy is also in attendance.

Image source, ReutersPresident Joe Biden's former Chief Medical Advisor, Anthony Fauci - who oversaw the US response to the Covid-19 pandemic - says he has been subject of "politically motivated threats of investigation and prosecution".
Reacting to Biden's pre-emptive pardons, of which Fauci is included, Fauci says: "Let me be perfectly clear: I have committed no crime and there are no possible grounds for any allegation or threat of criminal investigation or prosecution of me."
As we mentioned earlier, Fauci has been frequently criticised by Trump and his political allies.
"The fact is, however, that the mere articulation of these baseless threats, and the potential that they will be acted upon, create immeasurable and intolerable distress for me and my family," Fauci continues in a statement.
"For these reasons, I acknowledge and appreciate the action that President Biden has taken today on my behalf," the statement ends.
Joe Biden and Donald Trump leave for the Capitol
President Joe Biden and President-elect Donald Trump have left the White House, travelling together to the Capitol in a limousine.
Image source, ReutersMoving away from Washington DC for a moment, we've just heard from Russian President Vladimir Putin, who has congratulated incoming US President Donald Trump on his inauguration.
In a televised address to his national security council, he also acknowledged Trump's desire to resume contact with Russia, and president-elect's previous remarks on doing everything possible to prevent a third world war.
"Of course, we welcome this stance and congratulate the newly inaugurated US president on assuming office," Putin said.
The Kremlin leader added that he is open to dialogue with the Trump administration on the Ukraine war, and that his position is there "should not be a temporary ceasefire" but rather a "long-term peace founded on respect for the legitimate interests of all people and nations living in this region".
"Naturally, we will stand up for Russia's interests," Putin said.

There's been a flurry of activity in the last couple of hours, so while US presidents outgoing and incoming share a tea in the White House, let's take stock.
Trump's inauguration day kicked off with his first event at a church ceremony in Washington DC, where tech billionaires gathered alongside his family and allies.
The soon-to-be 47th US president is now with his wife Melania and the Bidens, before their motorcade leaves shortly for the Capitol.
This all builds up to the swearing-in ceremony. Just after 11:00 local time (16:00 GMT), Vice-President-elect JD Vance will be introduced and sworn in at the Capital One Arena. Trump is expected to be sworn in before 12:00 EST (17:00 GMT), which will be followed by his inauguration address.
There's lot more to follow - a luncheon, parade and formal balls - but more on that later.
We'll be bringing you live updates, analysis from our correspondents and the latest pictures throughout the day, plus you can watch live at the top of this page to follow our live stream.

Trump's incoming team have confirmed reporting in the Wall Street Journal that while the incoming president will issue a memo directing federal agencies to study trade policies, there will not be new tariffs announced today.
The incoming Trump administration will also sign a presidential memorandum on inflation for an “all of government approach” to bring down prices “as soon as possible”, according to incoming White House administration officials.
They also said that Trump would make good on Trump’s campaign promise to "drill baby drill", taking a number of actions to boost American energy production.
One executive order is focused on Alaska. The state was described as having an incredible abundance of natural resources that previous administrations had failed to take advantage of. Critical minerals were mentioned as being crucial.
Additionally, Trump will sign an executive order declaring a National Energy Emergency. Officials said “high costs of energy” were unnecessary and had been punitive for people over the past four years.
The action is also crucial, they told reporters, because of the AI (artificial intelligence) race - the US needs to generate the power to stay at the forefront of this technology which requires a lot of energy.

More now from the incoming Trump administration, after an official spoke with reporters earlier today.
The official said that several criminal organisations will be designated as foreign terrorist organisations, FTOs, and specially designated global terrorists - a term that in the past has been applied to Al Qaeda, the so-called Islamic State, Hezbollah and other groups.
It is unclear how many groups will be designated, but the official specifically cited the MS-13 gang and Tren de Aragua, a Venezuelan-based group they described as “an irregular armed force” of Venezuela’s government.
Trump is also expected to end refugee admissions for a four-month period and “end” asylum by proclamation, which will allow US officials to swiftly deport would-be asylum seekers who present themselves at the US-Mexico border.

It was smiles and handshakes on the front steps of the White House this morning, as Donald and Melania Trump were greeted by Joe and Jill Biden.
The White House meeting for tea is one of those inauguration moments that serves as a visible sign of the peaceful transfer of power following a democratic election. It has typically been a source of American pride – that, despite partisan differences, the nation could come together for at least one day.
It was a tradition that was discarded four years ago, after the 6 January attack on the US Capitol by Trump supporters and the outgoing president’s decision not to meet with Biden or attend any of the inauguration ceremonies.
After that tumultuous exit, Biden pledged to heal America’s divisions during his presidency – a task that, given the acrimony of the past four years, has been left unfinished.
But at least for today, the old norms and traditions of the presidency have returned.

Image source, ReutersJoe Biden said "welcome home" to Donald Trump as he arrived at the North Portico of the White House a few moments ago.
Neither president responded to shouted questions from reporters before walking into the White House.
Just before Trump's arrival, Biden was asked how he was feeling today - his last day at the White House.
"Good," he responded.
The tea meeting will take place behind closed doors, with no press allowed inside.
The tea tradition began in 1837, with Presidents Martin Van Buren and Andrew Jackson.
In 2021, however, Trump did not host Biden for tea, breaking that tradition amid continued false claims from Trump that he had won the 2020 election.
In a departure from tradition, today's inauguration will take place inside the Capitol.
Historically, presidents take the oath outside in front of vast crowds packed onto chairs on the mall.
However, bitterly cold temperatures - forecasters have predicted lows of -11C (12F) - in Washington DC means that proceedings have been shifted inside to the Capitol's Rotunda.

Blue is a very on-brand colour for the entire Biden family , externaland it has come to represent the administration of the last four years.
At her husband's swearing-in ceremony in 2021, Jill wore a blue coat created by designer/founder Alexandra O’Neill for the New York-based luxury womenswear label Markarian – it reportedly quintupled sales for the designer, external.
It was custom-made and embroidered with Swarovski crystals, plus had a pandemic-era matching face mask.

Donald Trump will aim to end birthright citizenship, according to a briefing recently held with reporters and a member of his incoming White House team.
That would mean the children of undocumented migrants living in the US will no longer automatically be considered US citizens.
The official provided no details on how the administration hopes to accomplish this.
Birthright citizenship is enshrined in the US constition, and an executive order by a president would not be able to change that.
To remove it would require a two-thirds vote in both chambers of Congress, as well as being ratified by three-fourths of state legislatures. It's a very high bar to make such changes.
