The socialite is a regular on the front row, and she pulled out all the fashion stops yet again at the Carven Spring Summer 2014 show yesterday (26 September).
The best bit? She wore a high street dress!
Yep, Olivia proved even designer-clad fashionistas love a bargain buy in this thigh-skimming minidress, £69.99 from Zara.
The gorgeous frock featured a navy tartan print, structured shoulders and statement zip detail around the waist. It's still available to buy online, but we predict a sell-out now it's got Olivia's seal of approval!
And don't even get us started on those over-the-knee boots. They're this season's hottest footwear trend, and Olivia totally nailed the look in her grey suede Stuart Weitzman numbers.
But unlike her frock, these babies will set you back a pretty penny, costing £610.
Oh Olivia, why do you do this to us?
