The Made In Chelsea star hit swanky nightspot Whisky Mist to celebrate the launch of her pal and co-star Binky Felstead's new book, Being Binky.
And, as always, Rosie ensured she was looking pretty fab for the occasion!
The stylista flashed a glimpse of her tum in a lace bralet teamed with a black jacket which featured 1980s-style shoulder pads.
But the best part of her look had to be her grey embellished skirt, which was a high street buy from H&M (see, Chelsea girls like a bargain too!).
Rosie topped off her ensemble with a fierce pair of lace-up heels by Steve Madden, plus a quilted handbag and a dazzling statement necklace.
And for the finishing touch, the fashion blogger slicked on a bright tomato red lippy. We wonder if she used her fave NARS Velvet Matte Lip Pencil in Red Square?
