The brunette beauty bagged an invite to a party hosted by supermodel Naomi Campbell to celebrate the opening of the new Fashion For Relief pop-up shop in Westfield shopping centre.
Rosie always impresses with her perfectly put-together ensembles, and this occasion was certainly no exception!
The fashion blogger was the belle of the ball in a sophisticated black gown complete with a high-low hemline, a strapless sweetheart neckline and a pretty peplum detail at the waist.
Rosie's dress is actually from her own collection for Lipstick Boutique which she launched earlier this month. It's called the 'Venice' dress and is available to buy now for £85.
She added a pop of colour to her all-black look with a 'Popsicle' stole by Charlotte Simone, while amping up the drama with a pair of caged peep-toe heels.
The starlet opted for a jet black manicure teamed with a statement cocktail ring and a chunky gold boyfriend watch, toting all her essentials in a Lulu Guinness lip-shaped shoulder bag.
And Rosie also took the opportunity to showcase her new haircut after visiting Duck & Dry in Chelsea earlier that day to get a few inches chopped off her lengths.
Her fresh barnet was tonged into gentle waves and she lacquered her lashes with heaps of mascara, finishing with rosy blusher and a flourish of red lippy on her pout. Gorgeous!
