The Made In Chelsea star looked totally dapper as she pulled a pose in her chic two-piece, which she paired with a prim checked top.
While Rosie's suit looks like it could be an ultra-pricey designer buy, it's actually from high street store The Kooples and is currently half price.
Pick up the tailored blazer with jersey sleeves for £120, together with the matching trousers for £67.50. OK, so it may still be an investment buy... but we're lusting after it all the same!
The starlet added a floaty top from Zara plus an impressive pair of strappy heels, also from Zara. Ever the polished fashionista, Rosie matched her pedi to her suit while opting for a classic black manicure.
To finish? A nude pout, lashings of mascara and wind-swept locks.
Top marks, Rosie!
