The former Made In Chelsea star unleashed her inner princess while celebrating the Feast of Saint Barbara in Munich.
Her stunning floor-length frock was a vintage number designed by David Emanuel, who designed Princess Diana's wedding dress and who is currently starring in ITV's I'm A Celebrity... Get Me Out Of Here!
With its velvet bodice and tiered skirt dotted with silver sequins, her gorgeous dress looked like something straight out of a Disney movie.
And with Kimberley opening the ball this year, it was only fair she stole the scene on the fashion front!
Taking to Twitter, the blonde bombshell said: "Cant believe I have been asked 2 Open the Ball in Germany, same as Elle Macpherson did last year, my icon! Can't believe they want me this year!"
Beauty-wise she kept things simple, applying lashings of mascara and nude lipgloss. She wore a pillar-box red hue on her nails while flaunting bouncy tresses styled in a side parting.
Other attendees at the event included former Gossip Girl actress Kelly Rutherford, Desperate Housewives star Marcia Cross and model Victoria Silvstedt.
