Holly Willoughby looked polished and ready for the party season in her latest ad post for M&S.

The star took to Instagram to share her chic ensemble with her 8.1 million followers, showcasing a dramatic midi dress featuring subtle celestial detail - it is covered in tiny stars, rather than polka dots as it first appears.

The black M&S dress is a classic choice and has an air of gothic glamour, thanks to the dual layers and covered buttons, which run down the length of the dress.

Holly's dress is the Star Print Button Through Midi Smock Dress from M&S and is currently available (at time of writing) for £45 in petite, regular and long, ranging from sizes 6 to 24.

In a caption, Holly explained that the dress was one of her "favourite pieces from [her] November edit" and also revealed the items she chose to style it with.

The sparking belt features a statement square buckle and cinches in her waist to great a classic hourglass, while the full skirt prevents the look being clingy. Holly finished the look with a pair of velvet heeled sandals featuring a cross-over design.

You can also find Holly's shoes on the M&S website, in sizes 3 to 8.
