The Christmas countdown is officially on! And how do we know? Because the Marks & Spencer Christmas advert has just hit screen. And the star is a certain Holly Willoughby – and her enviable wardrobe. We can’t stop thinking about the fabulous purple coat that she wears during the ad – which is FINALLY available to purchase now.

Although it was released in store earlier this month, you can now purchase it online for £89. The single-breasted design has already proved a massive hit on Instagram, due to not only the gorgeous wide lapels, the on-trend, oversize fit and super cosy wool texture – but also the fact that Vogue Williams, Holly and fashion blogger Erica Davies have all rocked it. Now if you don’t know who Erica Davies is – let us enlighten you. Erica is a huge fashion influencer and has always been a big fan of M&S, having single-handedly made THAT starry-print constellation dress a sellout last year.
