On Thursday evening (1 September), Frankie joined BFF Georgia Toffolo at the Rituals store opening in London and she stole the show (those legs, though!) as she made her debut in this thigh-skimming, tan-flaunting mini dress that boasted a cutesy floral print and a plunging neckline to boot.
Now, we assumed Chelsea resident Frankie would be a bit of a designer fiend (YSL, Chanel - we can dream, right?) but she proved us entirely wrong as she took to Instagram to share the deets of her OOTN (outfit of the night, obvs!).
Giving her new fans and followers tonnes of wardrobe inspiration, Frankie mentioned that she snapped up her fabulously flirty floral number from none other than Lipsy (Jessica Wright and Ariana Grande are huge fans) and that you can snag an exact match right now.
Fair enough, it may be a little too summery for September, but can't knock us for trying to cling on to the good weather, eh?
Elsewhere in the city, Love Island's Kady McDermott was celebrating her 21st birthday bash alongside beau Scott Thomas and pal Emma-Jane Woodhams.
Michelle Keegan and Mark Wright were also spotted partying in London after the Our Girl photocall.
