The Harry Potter actress was seen in New York on Thursday (15 August) and first made an appearance in a long, white dress that was cinched in at the waist with a skinny gold belt.
She accessorised her smart frock with a pair of sandals and wore minimal make-up.
Emma, 23, was later spotted back out in the Big Apple, but this time she had layered a large blue Great Gatsby jumper over her formal attire.
The sweatshirt featured the iconic book cover design, with author F. Scott Fitzgerald's name also written along the bottom.
Although this isn't a combination we would normally try out, we have to say that Emma pulls it off effortlessly and pays homage to her love for books at the same time. Very cool!
Despite often appearing on the celeb best dressed lists, Emma - who most recently starred in The Bling Ring film - apparently only owns four pairs of shoes!
Earlier this month, the A-list actress revealed that she has a super simple wardrobe and chooses the most inconspicuous clothes to wear so she is unlikely to get recognised.
"I'm always trying to dress myself down in a way that I think won't draw attention," she told the Daily Star.
