Grace showed off her tanned legs in a frilly blue mini skirt as she joined a host of celebrities, including Harry Derbidge and Louie Spence, at Amy's third anniversary party for her clothing collection.
Grace completed her outfit with a cosy red cropped jumper, a red suede clutch bag and blue t-bar heels.
Reality star Grace, who is yet to appear in the new series of TOWIE, made sure she was pampered ahead of her night out, tellings fans on Twitter: "Bubble bath and candles before I head up to @MissAmyChilds launch tonight! #refreshed can't wait."
After mingling with celebs at the bash, Grace was all smiles as she was pictured making her way home from the party, which was held at the Dirty Martini cocktail bar in central London.
While Grace was on hand to celebrate Amy's success, last week, she celebrated the launch of her own fashion range, the Gracie Collection.
The stunning brunette was joined by TOWIE's Danielle Armstrong and Jasmin Walia at the celebratory launch held at Sugar Hut nightclub in Essex.
