Following the huge success of their What Not To Wear debut last year, soul sensation Mica Paris and supermodel Lisa Butcher are back for a new series. And, in a What Not To Wear first, they encounter double trouble as they take on the task of helping identical twins find their individual identities.

When identical twins from across the country descend on the What Not To Wear house, heads are turning, but certainly not for sartorial reasons. Among those who make the shortlist for the chance to be transformed are Mary and Nancy. Both married, with children, Mary and Nancy are like peas in a pod – not only working for the same company, but also living together, with their two families sharing the same house. Indeed, Mary’s husband is known as “Johnny two wives” at work. Style-wise they live in black, buy two of everything and often wear the same outfits at the same time – something which they also do with their own young daughters.

Pippa and Jenny also make the shortlist thanks to their wardrobe, which can be summed up in three words – blue, baggy and fleeces. Their stunning figures never see the light of day.

Faced with multiple problems, Mica and Lisa make a surprise decision. Having initially planned on taking one set of twins, they decide instead to choose one twin from two different sets. For the twins who are chosen, and those who are left behind, this proves to be a huge shock, with tears and anger all around.

Just how will the chosen two fare without their sisters by their side, and what will be the reaction of their twins when they see their siblings transformed? The results are a gripping insight into the special bond betweens twins and how this relationship influences their individual identities.
