Millie Mackintosh Models Rosie’s Hot New Sleepwear

Remember when Rosie Huntington-Whiteley rocked up to the launch of her new M&S Autograph collection in that ah-mazing flowing silk nightdress?

Yes, well just when we thought no one could look more amazing than the statuesque supermodel herself in the slinky champagne gown, Millie Mackintosh went and wore it.

From its sexy thigh-split to its lace-trimmed straps and low V back, it’s the pretty slip of our dreams, and Mills showed exactly how a ready-for-bed goddess should work it.

Getting a sneaky shot of the gorgeous cross-back as she threw her hair seductively over one shoulder, the former Made In Chelsea star wrote: ‘What Monday nights are made for! Thank you @rosiehw #rosieforautograph #silk #nightdress.’

While Rosie’s new design is most certainly meant for indoors, it’s almost too gorgeous to keep behind closed doors. As the lady herself showed last month when she threw on a faux fur bolero and worked it to a fashion bash.

Well, if you can pull it off…
