The hottest duo in the world of fashion around the time of Christmas? A two-piece party suit, of course. And their beauty shines brighter than that of a dress, for here is a chic and put-together ensemble that looks as good mid-dancefloor lunge as it does performing the caterpillar across the floor at the work party.

Their real virtue, however, lies in the fact that, as is so often the case with two-pieces, these are two entirely separate style entities in and of themselves. The jacket can be swapped out for a structured addition to a T-shirt and jeans get-up, while the trousers (the preferred style would ideally be wide-leg) can be paired with chunky trainers and a fitted It knit.

Kai Collective’s are crafted from plisse fabric in all colours of the rainbow – the emerald green gets our vote – while Sleeper’s feather-lined pyjamas, which make for decidedly perfect party pieces too, promise to add a splash of free-loving fashion fun.

Colour is key
