The Made In Chelsea star has been snapped up as the face of Pretaportobello.com's MarketSpace initiative, which supports young independent British designers.
Fashion blogger Rosie knows how to pull an outfit together and she looks totally amazing while posing for the promo shots, showcasing a glimpse of her stylish wardrobe.
One snap sees the Chelsea gal rocking an emerald green jumpsuit with cold shoulder detailing, teamed with towering cut-out heels and a wide-brimmed hat.
In another photo, Rosie flaunts her svelte pins in a retro-inspired colour block minidress, before sporting a toasty red knitted two-piece paired with over-the-knee socks.
Her golden brown locks are styled in her signature loose waves, and her blue peepers are decorated with warm smoky brown eyeshadow and lashings of jet black mascara.
Meanwhile, as well as filming for Made In Chelsea, Rosie has been working hard creating her debut fashion collection for Lipstick Boutique which launched last month.
Her autumn/winter '14 range boasts elegant black gowns, chunky knit jumpers and dainty lace crop tops, plus full, prom-style skirts and cosy faux fur shawls.
