Ohhhhh, snap! I've been eyeing Olivia's Fashion Week outfits all week and couldn't help but notice her grey suede shoe crush. She's clearly hooked on these Proenza Schouler square toe booties, making them work with her mismatched dress and cardi ensemble, Tibi printed dress and more demure shift. I love how a style icon like Olivia will happily re-wear the same statement shoes day after day; makes her seem a little more human, dontcha think? You can get Liv's exact booties for around $680 at mytheresa.com. Yipee!
