Olivia Wilde forgot to pack her bra for Paris Fashion Week in totally see-through bodysuit

Paris Fashion Week is officially well underway, and it is the second time this year the style set has descended on the French capital. Confused? Well, back in January it was the haute couture shows taking place from design houses including Schiaparelli and Chanel, with Zendaya, Jennifer Lopez, Hunter Schafer and Noah Cyrus all bagging a front row seat.

This time around, it's the turn of the autumn winter ready-to-wear collections from the likes of Dior, The Row and Victoria Beckham. The final destination of fashion month – following New York, London and Milan – Paris never fails to disappoint. As demonstrated on day one by Julia Fox on the Pressiat runway serving Yeti chic in an XXL furry jacket.

And day two was no different, but rather than the runways it was Olivia Wilde's attendance at the Saint Laurent show that was turning heads. The actress arrived in a completely see-through bodysuit, freeing the nip in the process. 

As well as being totally transparent, the scoop-neck spaghetti strap design was almost entirely backless too, with just a single strap keeping it in place. Clearly a fashion statement that tapped into naked dressing, or maybe she just forgot to pack her bra?

Olivia paired the sheer number with a belted utilitarian midi pencil skirt, tights and slingback leather heels. Leather elbow-length gloves, a gold choker necklace and '70s tinted aviator sunglasses completed the look that ticked off a number of the season's biggest fashion trends.

If this is the level of sartorial success we can expect with several days and shows remaining of Paris Fashion Week, we can't wait to see what our favourite celebs wear next.
