This is why Blake Lively always wears suits (at the moment)

In case you hadn't noticed, Blake Lively has been rocking a strong suit look while promoting her new film, A Simple Favour, with Anna Kendrick these past few weeks.

Rather than opting for the traditional red carpet dress, she has instead gone for checked and colourful tailoring from the likes of Versace, Zimmermann and Roland Mouret.

Wearing Givenchy Haute Couture

This prompted a lot of people to speculate it had something to do with her new role (she did delete her whole Instagram because of it after all), and she has addressed those rumours.

Explaining her tuxedo to E! News at the Ralph Lauren 50th Anniversary show, she said, 'This outfit is inspired by [A Simple Favour director Paul Feig] without even meaning to.'

In case you were wondering, she was wearing a black tux with waistcoat, complete with a top hat and cane.

She added, 'In a A Simple Favour, the movie we have coming out on 14 September —shameless self-promotion here — I modelled my entire character's look after him,' she revealed. 'So tonight, we were coming at dates and didn't realise we're wearing the same outfit—it's so embarrassing.'

So there you have it, it is sort of to do with the film, just not with her character.

Penny grew up in France and studied languages and law at the Sorbonne Nouvelle University in Paris before moving to the UK for her MA in multimedia journalism at Bournemouth University. She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
