Is there hidden meaning behind why Melania Trump wore white?

In breaking with tradition, Melania Trump arrived separately from her husband, President Donald Trump, for his first State of the Union address, further leading to speculation that all is not well behind White House closed doors.

The couple, who have not been seen publicly together since New Year's Eve, broke protocol to arrive to the Capitol building in separate cars on Tuesday, despite the short journey from the White House.

Instead, Melania opted to ride with the guests she had invited to sit in the first lady's box.

The US first lady wore an ivory Christian Dior pantsuit to the first State of the Union address from her husband 

Twitter went wild with speculation when first lady Melania Trump showed up for her husband's first State of the Union address in an ivory Christian Dior pantsuit.

Some suggested sarcastically her attire was a tribute to Hillary Clinton, her husband's 2016 Democratic opponent, who favours pantsuits.

Or, was she honouring the suffragettes, who made white their signature colour? Others tweeted that Mrs. Trump looked "divine."

Her suit was in contrast to the black worn by Democratic congresswomen and their allies.

Tuesday marked the first time Mrs Trump was seen in public with her husband since The Wall Street Journal reported that Donald Trump's lawyer paid $130,000 (Dh477,483) in 2016 to keep quiet about an affair.
