It was a rainy morning in Paris as world leaders and their partners turned out to mark Armistice Day, but the drizzly atmosphere did nothing to put a dampener on the First Ladies' style.

Melania Trump, 48, led the way in a chic grey ensemble as she arrived for the international ceremony for the Centenary of the WWI Armistice at the Arc de Triomphe.

The First Lady was elegant in a belted grey dress with a full pleated skirt with a pussy bow feature at the neckline, teamed with a grey overcoat she wore over her shoulders in a trendy 'shrobing' style.

Not to be outdone, her French counterpart Brigitte Macron wore three different outfits, for this morning's events beginning the day in a smart black overcoat with silver buttons, teamed with sleek black trousers as she welcomed guests at the Élysée Palace.

Naturally as wife of the host, French President Emmanuel Macron, Brigitte Macron put her best foot forward, looking perfect co-ordinated with her husband in a smary navy dress and jacket.

But she faced stiff competition in the style stakes from First Lady Melania Trump who opted for androgynous chic in a smart tuxedo.

Meanwhile, Princess Charlene of Monaco also looked achingly chic in a floor length black gown, which showcased her statuesque figure.

On Saturday afternoon, Donald Trump called off a a trip to Aisne-Marne American Cemetery and Memorial after a bad weather call grounded Marine One.

He and first lady Melania Trump had planned to visit the memorial for American marines near the Belleau Wood battlefield on Saturday afternoon.

However the event was cancelled at the last minute due to a storm that would have prevented them from helicoptering to the site that's more than an hour's drive from Paris.

'The President and First Lady’s trip to Ainse-Marne American Cemetery and Memorial has been canceled due to scheduling and logistical difficulties caused by the weather,' the White House said. 'An American delegation led by Chief of Staff General John Kelly and Chairman of the Joint Chiefs of Staff General Joe Dunford will attend on their behalf.'
