Ivanka, 35, and Melania Trump, 47, are both in New York with Donald Trump for the UN General Assembly.
Yesterday, Melania wore a sleek grey check trouser suit and black shirt for the first day of proceedings.
And it seems Ivanka approved of the outfit choice, wearing very similar attire today.
Ivanka’s suit had several similarities to Melania’s – both had trousers cropped at the ankle, and both jackets had pockets to the front.
But whilst the First Lady teamed her suit with black, Ivanka made a more unusual colour choice.
She wore a silk blue shirt and blue lace kitten heels.
The first daughter wore her hair slicked back in a low bun.
She covered her eyes with a pair of classic aviator sunglasses and had a pair of slim hoops on her ears.
The mum-of-three kept her makeup simple, with bronze contouring and a berry gloss on her lips.
Her outfit today was in stark contrast to her fashion-forward choice yesterday.
Ivanka wore a pair of disco ball drop earrings which swung and glittered in the light.
Her hair was put up in an intricate chignon so that it was away from her face and all eyes were on the earrings.
Ivanka teamed the earrings with a sleek black roll-neck top which she tucked into her skirt.
Showing off her style credentials, Ivanka wore a camel coloured skirt with a 3-D floral design.
Ivanka’s style credentials have gained her fans around the world – with some even wanting to look exactly like her.
Since summer 2016 there has been a rise in people wanting to look like Donald Trump’s daughter Ivanka.
