Ivanka, 35, was pictured walking across the South Lawn before departing the White House to make her way to Missouri to join Donald Trump.
Despite the bright sunshine and obvious heat, Ivanka chose to wear a thick linen dress.
The dress, which came to her knees, was sleeveless, but otherwise quite covered up.
Cream in colour, the dress also featured a striking blue graphic formal design.
Ivanka paired this with a pair of nude court heel shoes and her favourite Dior sunglasses.

Ivanka was joined by White House Staff Secretary Rob Porter and National Economic Council Director Gary Cohn.
She will attend a “tax reform kickoff event” with her father in Springfield, Missouri.
Ivanka recently enjoyed a trip to Camp David, returning to Washington on Sunday.
She was pictured stepping off Marine One on the South Lawn of the White House with husband Jared Kushner, 36, and their children, Arabella, 6, Joseph, 3, and Theodore, 1.
Ivanka decided to wear casual attired for the journey home, back to the White House.
She showed off her toned arms in a white sleeveless top, white trousers and a pair of beige trainers.
She tied her hair into a messy bun, slung a dark blue stripe jumper over her shoulders and covered her eyes with a pair of cat-eye sunglasses.
Her outfit leaving for Camp David was slightly more dressed-up.
