Dance-floors this Christmas are expected to be filled with metallic numbers, killer cocktail dresses and tartan suits this year if the Christmas in July press days are anything to go by.

Women will also be wrapping up in faux fur gilets and jackets to keep the cold at bay, while the trend for donning a Christmas jumper over the season shows no sign of abating – John Lewis is putting its bet on a £80 version.

Hero product: The jumpsuit

Like House of Fraser, John Lewis is jumping on the trend for jumpsuits for Christmas, predicting that a military-style Somerset by Alice Temperley version will fly off the shelves.

But the hero product hotly tipped is the jumpsuit. Hot in the 1970s, this playful one-piece continues to be a staple piece of many a woman’s wardrobe and could be chosen over the standard cocktail dress as the ultimate party outfit.
