The fashionista was spotted in New York yesterday (20 March) walking her totally adorable dog, Mr Butler. But cute animal aside, what really grabbed our attention was Olivia's chic ensemble.
Olivia pulled off one of the biggest denim trends at the moment – ripped jeans – teaming them with a crisp white shirt and casual boucle jacket.
She finished off the get-up with a pair of multi-coloured pointed heels that have gone straight to the top of our lust list.
The City star also added a touch of glam to her look with a bling-tastic, statement necklace – check it out! And she wore the cutest pair of cat eye sunnies – complete with tiny polka dots.
Olivia showcased a flawless complexion, which we've heard is down to her must-have product – Kiehl's Skin Rescuer. Her hair, as usual, looked impeccable, worn loose and silky smooth.
The American beauty added a subtle flush of pink to her lips, as well as a brighter hue to her talons which was the perfect match to her clutch. Talk about co-ordinating!
And of course, Olivia showed off her gorgeous engagement ring, courtesy of her hunky model beau, Johannes Huebl - who proposed to her earlier this year.
We can't imagine ever looking this good while walking our pooch, but we're going to try our best!
