In case you've been living under a rock, Olivia's collection landed earlier in the week (hurrah!) and it looks like Katie is just as in love with everything as we are, as she chose to dress her fabulous curves in this stunning glitter-splashed maxi from the drop.
Amazingly, it's one of a number of frocks that hasn't yet sold out, but we're pretty certain it'll fly off the rails once everyone catches a glimpse of Miss. Salmon over here.
Katie brought ALL of the glamour to Covent Garden's Tropicana Beach Club as she strutted her stuff in the sparkly dress (perfect for the party season, right?) which boasted a high thigh split, a Bardot-inspired neckline and slinky sleeves to boot.
The star - who has her very own range with Prodigal Fox - teamed the stunning number with a pair of lace-up boots that featured a killer stiletto heel and she showed off the simple yet oh-so-chic neckline by rocking her locks in a sky-high bun.
Can we also just take a moment to appreciate her flawless make-up? Highlight and brows on point!
During the evening, all three girls sipped on cocktails and prosecco before taking to the dance floor to show off their style.
Elsewhere in the city, Cara de la Hoyde showed her support for Olivia at the SPORTFX event in a gorgeous bloom-adorned bodysuit.
Now, er, if you need us, we'll be out shopping!
