It looks like reduced from £69.99 to £39.99
in the Zara summer sale. Her accessories budget is a slightly different (much larger and probably jewel encrusted) kettle of fish though, given that it comfortably includes Charlotte Olympia heels and Lulu Frost necklaces!
Sadly Olivia's dress has sold out, but given the star's apparent fondness for high street fashion we're eager to see what else she's packed for her Parisian jaunt.
Has Olivia inspired you to take a trip to Zara or Topshop? Let us know in the comments!
