It's a case of do as I say, not as I do.
Melania Trump has chosen to forgo a headscarf on her first international engagement as US First Lady in Saudi Arabia.
But in 2015, her husband Donald Trump heavily criticised then-First Lady Michelle Obama for not covering up.
"Many people are saying it was wonderful that Mrs Obama refused to wear a scarf in Saudi Arabia, but they were insulted," he wrote on Twitter on January 30, 2015. "We have enuf enemies [sic]."
The White House said neither Ms Obama nor Ms Trump were required by the Saudis to wear scarves, so they didn't, reports CNN.
The Trumps are in Saudi Arabia to strengthen defence ties between the kingdom and the US, the President signing a massive arms deal despite the oil-rich country's poor human rights record.
The Saudi dress code demands Muslim women wear a headscarf, but foreigners don't. The law isn't always enforced consistently however, with some areas more tolerant than others.
German Chancellor Angela Merkel and UK Prime Minister Theresa May have both recently gone without a headscarf in Saudi Arabia. Hillary Clinton, Mr Trump's former presidential rival, didn't cover up when she visited as Secretary of State under Barack Obama.
