Every so often M&S releases a fashion-forward item that we want even more than a packet of Percy Pigs, and Holly Willoughby just alerted us to a new hero piece from the retailer. Anyone who reads Who What Wear UK regularly will know that one of the biggest trends this season is red worn from head to toe, and Holly wore a red long-sleeved top with a nipped-in waist by Topshop with an amazing red asymmetric-hem skirt by M&S. But like all golden pieces from M&S, this is flying off the shelves, and it is already only available in select sizes. This skirt would be a perfect Christmas Day outfit—add a festive jumper, and you'll look like a stylish Mrs. Claus. Keep scrolling to see Holly Willoughby's amazing M&S find.
