The Made In Chelsea star looked fab in skin-tight leather while attending the Christian Lacroix for London Collections: Men event, held at the Mondrian London hotel.
Rosie - who recently returned from a sun-drenched holiday in Cape Town - put her flat-as-a-pancake tum on full display in a racy black lace bralet, which added heaps of va-va-voom to her outfit.
The Chelsea lass also sported a white jacket complete with a cape design with silver beadwork on the shoulders, plus a buckle that clipped across her waist.
She rocked her fave leather trousers while making a statement with her choice of footwear, donning a fab pair of embellishment peep-toe heels featuring zig-zag straps. HOW awesome?! We want a pair!
And while Rosie loves a monochrome outfit, she did add a slight pop of colour to her otherwise neutral look by toting a clutch bag with the word 'Girls' spelt out in rainbow letters.
The fashion blogger showcased her natural beauty by keeping her make-up simple, decorating her peepers with lashings of mascara teamed with a rosy pink lipstick while styling her brunette locks in loose, glossy waves. Gorgeous!
Other attendees at the event included Rosie's MIC pal Mark Francis Vandelli and Rizzle Kicks' Jordan Stephens.
