The 31-year-old supermodel and 'Transformers' actress has walked the catwalk for major labels such as Burberry, Victoria's Secret and Prada, and now the 'Mad Max: Fury Road' star has donned a new look and appeared without a bra in the French capital following a fitting with iconic British designer, Vivienne Westwood.

Rosie - who is engaged to 'The Meg' actor Jason Statham - stepped out wearing large over-sized shades, £650 Gianvito Rossi leopard print sandals, a grey knitted halter-neck top and pinstripe trousers to complete the look.

The Marks & Spencer lingerie designer finished off her effortless ensemble with a fitted tan leather double-breasted blazer by We11 Done which retails for £585. 

Rosie - who welcomed her and Jason's 14-month-old son Jack into the world in last June - made an appearance at the legendary Yves Saint Lauren fashion show at Paris Fashion Week on Tuesday night (25.09.18).

The model has been spotted at multiple front-rows at Milan and New York Fashion Week for luxury brands including Brandon Maxwell, Versace - who has recently been bought by billionaire fashion house Michael Kors for €1.83bn ($2.1bn) - and Ralph Lauren.

Rosie and Jason stepped out last Thursday (20.09.18) for a low-key date night in London's Mayfair, however, when they were leaving Isabel's restaurant, Jason had to step in when a photographer got to close.

The 'Snatch' actor put his hand out prompting the photographer to step back as the pair left their dinner to go home unscathed.
