The 'Heart Attack' singer rocked a monochrome colour palette as she arrived at the Good Morning America studios in New York yesterday (27 June).
Demi suited up in a Saint Laurent blazer paired with leather shorts, a V-neck American Apparel tee, and a classic Givenchy handbag.
And she gave her boyish look a feminine twist with red-soled Christian Louboutin heels and a matching killer pout.
So simple yet so chic - we just can't get enough of this look!
