She means business! Rosie Huntington-Whiteley turns heads in off-the-shoulder shirt and pinstripe trousers at fashion bash

She is one of the world's most stunning and in-demand supermodels. 

And on Wednesday, Rosie Huntington-Whiteley was no doubt at the top of the guest list for the CFDA/Vogue Fashion Fund Show and Tea event at the Chateau Marmont in West Hollywood. 

The English supermodel looked ready for business as she arrived to the Kate Spade-presented outing, clad in an office wear-inspired ensemble.

Smarten up in pinstripes by Monse

The CFDA Vogue event in Los Angeles yesterday was a roll call of top celebrities all wearing high end designer labels.

From January Jones in Cushnie et Ochs to Emma Stone in Brock Collection and Alessandra Ambrosio in Baja East to Maria Sharapova in Roksanda, the top brands just kept on coming at this fashion shindig.

And let's not forget Rosie Huntington-Whiteley who looked just amazing in this outfit from the Monse SS17 line. We love the white shirt worn off the shoulder with those wide leg pinstripe trousers. It's a sartorial tour de force and we're obsessed.

If you are too then why not pick up some current season pinstripes from Monse at Net-a-Porter now (right)? Or you can get the look with our edit of smart styles below. Sisley has a gathered waist option that's reminiscent of the original or do a draped waistline by Paper London.

Wear with crisp white tees and sneakers for a cool work look this season.

Rosie customized her solid white button-down by letting the side slide off her shoulder, but avoided revealing more than she intended to.

She sported a peculiar belt, which appeared to be the bottom half of a blazer.

Wednesday's event appeared to be a ladies' outing. 

But when Rosie's not mingling with her gal pals, the high-end fashion model spends time with fiance Jason Statham. 

The two began dating in 2010 before becoming engaged in January of this year.
