The internet is divided on Melania's outfit at the Holocaust memorial

For his first foreign trip since taking office, President Donald Trump traveled to Saudi Arabia and Israel, meeting with each country's respective leaders. Accompanied by Jared Kushner, Melania and Ivanka Trump, the first family was welcomed by Prime Minister Netanyahu and his wife Sara on the tarmac in Tel Aviv.

Upon disembarking the plane, however, a questionable few-second interaction between Trump and Melania went viral. It appears that the president reached for the first lady's hand, but Melania swatted his hand away. The strange moment caused much speculation on social media -- but some assume Melania was just being conscious of the orthodox tradition.

Later in their journey, the Trumps visited both the Western Wall and Yad Vashem, Israel's Holocaust memorial. Both Ivanka and Melania wore white to pay their respects at the center -- but, it was Melania's outfit that has drawn a bit of criticism.

visit to Yad Vashem:

FLOTUS' dress, which was decorated in off-white stripes, was long enough to shield her calves. However, although the dress was gorgeous, many weren't happy with its lack of sleeves and Melania's bare shoulders. In questioning the appropriateness of the dress, some suggested she wear a shawl or other type of covering.

Ivanka, who converted to Judaism when she married Jared, sported a $5700 lace Oscar de La Renta gown. The white silhouette covered the first daughter's arms and legs.

Together, POTUS and Melania presented a wreath at Yad Vashem, while Ivanka and her husband looked on.

In her Instagram photo, she included a quote from Viktor E. Frankl. "But there was no need to be ashamed of tears, for tears bore witness that a man had the greatest of courage, the courage to suffer," it read.
