If I wore this, I'd be arrested under for indecent exposure, crimes against fashion/taste and for possibly having a screw loose.
But Rosie, she looks amazing. She was front row at the Atelier Versace show at Paris Fashion Week and lookit, to paraphrase the young people her look was on fleek.
No, I've no idea what it means either. But I do know her make up, hair and style was stunning.
Here she is telling Natasha Poly why she wins the blonde, cheek-boned, black bralet dress-wearing competition. And not even the unicorn that is Ms Poly can disagree with her.
Tousled lob, neutral lip and a healthy dose of highlighting (sorry, we're calling it strobing now) - I want to be Rosie when I grow up. As long as I adopt a Benjamin Button form of ageing.
If you're leaving Naomi and Irina in the ha'penny place, you know that you're doing something right.
You can take a look at the gallery below and see if you agree with Rosie as style crush of the week. Will you be taking inspiration from her hair/make up look this weekend?
