Last week Rosie Huntington-Whiteley launched her first ever lingerie collection for high street retailer M&S, inspired by the 1920s and her own work as an underwear model and she marked the occasion with a form-fitting and fabulous LBD- of course!

The secretary-chic style suited Rosie's supermodel proportions but would look just as good on more petite figures as the pencil design will cinch you in and we all know the figure-flattering qualities of the black peplum! We love how Rosie kept it simple with a burgundy belt and metallic pointed stilettos making this an achievable look even for us normal folk. Get Rosie's season-savvy style here:
