Believe it or not, it isn't designer - hurrah!
Fashion-savvy Frankie looked fabulous as ever as she slipped into this eye-catching, party-perfect skater dress that featured embroidered flowers in baby blue (cute!), a sweetheart neckline and a sheer overlay including long sleeves.
Now, there's no denying Frankie loves a good luxe buy (have you seen the rest of her wardrobe? Er, jealous!) but she took to Instagram to reveal that she actually paid a little visit to the high-street for the snappy little number that showed off her legs for days.
Letting her fans and followers in on her style secrets, Frankie pinpointed her party dress as a Lipsy number and of course, it wasn't;t long before the compliments came in!
"Frankie you are FINE," wrote one of her followers, while another simply said, "This outfit, this outfit, this outfit!"
Gorgeous Ms. Gaff teamed her Insta-worthy dress with a pair of tie-up nude sandals with a duo of cutesy tassels and, unlike the other guests, ditched the big bouncy blow-dry for a dishevelled bun.
Major beauty points, Frank!
