The former Made In Chelsea star put on her best denim as she headed to the Jeans for Genes party at London's Jewel Bar on Tuesday night (3 September).
Kimberley, who has just returned from a holiday to Greece, was all smiles as she posed alongside the two models for the campaign.
Keeping it simple yet chic, the swimwear designer teamed her skinny jeans with a fitted white vest top and nude pointed heels.
Kimberley also showed off her model credentials as she struck various poses for the photographers!
Making the most of her night, she then headed to Annabel's Private members club and restaurant, where she rocked a Jeans for Genes T-shirt.
She was later spotted arriving at The May Fair hotel, and seemed to be in good spirits as she clutched onto her mobile phone, while walking into the venue.
Taking to Twitter earlier today, she said: "Just got back from Greece, fun night at #Jeansforgenes last night and dinner with my friends at Annabelle's .. Love London."
